Support for driving multiple EL nodes from a single Nimbus BN (#4465)
* Support for driving multiple EL nodes from a single Nimbus BN

Full list of changes:

* Eth1Monitor has been renamed to ELManager to match its current
  responsibilities better.

* The ELManager is no longer optional in the code (it won't have
  a nil value under any circumstances).

* The support for subscribing for headers was removed as it only
  worked with WebSockets and contributed significant complexity
  while bringing only a very minor advantage.

* The `--web3-url` parameter has been deprecated in favor of a
  new `--el` parameter. The new parameter has a reasonable default
  value and supports specifying a different JWT for each connection.
  Each connection can also be configured with a different set of
  responsibilities (e.g. download deposits, validate blocks and/or
  produce blocks). On the command-line, these properties can be
  configured through URL properties stored in the #anchor part of
  the URL. In TOML files, they come with a very natural syntax
  (althrough the URL scheme is also supported).

* The previously scattered EL-related state and logic is now moved
  to `eth1_monitor.nim` (this module will be renamed to `el_manager.nim`
  in a follow-up commit). State is assigned properly either to the
  `ELManager` or the to individual `ELConnection` objects where
  appropriate.

  The ELManager executes all Engine API requests against all attached
  EL nodes, in parallel. It compares their results and if there is a
  disagreement regarding the validity of a certain payload, this is
  detected and the beacon node is protected from publishing a block
  with a potential execution layer consensus bug in it.

  The BN provides metrics per EL node for the number of successful or
  failed requests for each type Engine API requests. If an EL node
  goes offline and connectivity is resoted later, we report the
  problem and the remedy in edge-triggered fashion.

* More progress towards implementing Deneb block production in the VC
  and comparing the value of blocks produced by the EL and the builder
  API.

* Adds a Makefile target for the zhejiang testnet

Local sim impovements (#4551)
* Local sim impovements

* Added support for running Capella and EIP-4844 simulations
  by downloading the correct version of Geth.

* Added support for using Nimbus remote signer and Web3Signer.
  Use 2 out of 3 threshold signing configuration in the mainnet
  configuration and regular remote signing in the minimal one.

* The local testnet simulation can now use a payload builder.
  This is currently not activated in CI due to lack of automated
  procedures for installing third-party relays or builders.

  You are adviced to use mergemock for now, but for most realistic
  results, we can create a simple builder based on the nimbus-eth1
  codebase that will be able to propose transactions from the regular
  network mempool.

* Start the simulation from a merged state. This would allow us
  to start removing pre-merge functionality such as the gossip
  subsciption logic. The commit also removes the merge-forcing
  hack installed after the TTD removal.

* Consolidate all the tools used in the local simulation into a
  single `ncli_testnet` binary.

cache LC headers and sync committees for bootstrap (#4499)
To allow LC data retention longer than the one for historic states,
introduce persistent DB caches for `current_sync_committee` and
`LightClientHeader` for finalized epoch boundary blocks.
This way, historic `LightClientBootstrap` requests may still be honored
even after pruning. Note that historic `LightClientUpdate` requests are
already answered using fully persisted objects, so don't need changes.

Sync committees and headers are cached on finalization of new data.
For existing data, info is lazily cached on first access.

LC data fork cleanup (#4506)
Distinguish between those code locations that need to be updated on each
light client data format change, and those others that should generally
be fine, as long as a valid light client object is processed.

The former are tagged with static assert for `LightClientDataFork.high`.

The latter are changed to `lcDataFork > LightClientDataFork.None` to
indicate that they depend only on presence of any valid object.
Also bundled a few minor cleanups and fixes.

Also add `Forky` type for `LightClientStore` and minor fixes / cleanups.

make LC data fork aware (#4493)
In a future fork, light client data will be extended with execution info
to support more use cases. To anticipate such an upgrade, introduce
`Forky` and `Forked` types, and ready the database schema.
Because the mapping of sync committee periods to fork versions is not
necessarily unique (fork schedule not in sync with period boundaries),
an additional column is added to `period` -> `LightClientUpdate` table.

History pruning (fixes #4419) (#4445)
Introduce (optional) pruning of historical data - a pruned node will
continue to answer queries for historical data up to
`MIN_EPOCHS_FOR_BLOCK_REQUESTS` epochs, or roughly 5 months, capping
typical database usage at around 60-70gb.

To enable pruning, add `--history=prune` to the command line - on the
first start, old data will be cleared (which may take a while) - after
that, data is pruned continuously.

When pruning an existing database, the database will not shrink -
instead, the freed space is recycled as the node continues to run - to
free up space, perform a trusted node sync with a fresh database.

When switching on archive mode in a pruned node, history is retained
from that point onwards.

History pruning is scheduled to be enabled by default in a future
release.

In this PR, `minimal` mode from #4419 is not implemented meaning
retention periods for states and blocks are always the same - depending
on user demand, a future PR may implement `minimal` as well.

Always-on optimistic mode (#4458)
With https://github.com/status-im/nimbus-eth2/pull/4420 implemented, the
checks that we perform are equivalent to those of a `SYNCING` EL - as
such, we can treat missing EL the same as SYNCING and proceed with an
optimistic sync.

This mode of operation significantly speeds up recovery after an offline
EL event because the CL is already synced and can immediately inform the
EL of the latest head.

It also allows using a beacon node for consensus archival queries
without an execution client.

* deprecate `--optimistic` flag
* log block details on EL error, soften log level because we can now
continue to operate
* `UnviableFork` -> `Invalid` when block hash verification fails -
failed hash verification is not a fork-related block issue

Backfill only up to MIN_EPOCHS_FOR_BLOCK_REQUESTS blocks (#4421)
When backfilling, we only need to download blocks that are newer than
MIN_EPOCHS_FOR_BLOCK_REQUESTS - the rest cannot reliably be fetched from
the network and does not have to be provided to others.

This change affects only trusted-node-synced clients - genesis sync
continues to work as before (because it needs to construct a state by
building it from genesis).

Those wishing to complete a backfill should do so with era files
instead.

State-only checkpoint state startup (#4251)
Currently, we require genesis and a checkpoint block and state to start
from an arbitrary slot - this PR relaxes this requirement so that we can
start with a state alone.

The current trusted-node-sync algorithm works by first downloading
blocks until we find an epoch aligned non-empty slot, then downloads the
state via slot.

However, current
[proposals](https://github.com/ethereum/beacon-APIs/pull/226) for
checkpointing prefer finalized state as
the main reference - this allows more simple access control and caching
on the server side - in particular, this should help checkpoint-syncing
from sources that have a fast `finalized` state download (like infura
and teku) but are slow when accessing state via slot.

Earlier versions of Nimbus will not be able to read databases created
without a checkpoint block and genesis. In most cases, backfilling makes
the database compatible except where genesis is also missing (custom
networks).

* backfill checkpoint block from libp2p instead of checkpoint source,
when doing trusted node sync
* allow starting the client without genesis / checkpoint block
* perform epoch start slot lookahead when loading tail state, so as to
deal with the case where the epoch start slot does not have a block
* replace `--blockId` with `--state-id` in TNS command line
* when replaying, also look at the parent of the last-known-block (even
if we don't have the parent block data, we can still replay from a
"parent" state) - in particular, this clears the way for implementing
state pruning
* deprecate `--finalized-checkpoint-block` option (no longer needed)

use LRU strategy for shuffling/epoch caches (#4196)
When EL `newPayload` is slow (e.g., Raspberry Pi with Besu), the epoch
and shuffling caches tend to fill up with multiple copies per epoch when
processing gossip and performing validator duties close to wall slot.
The old strategy of evicting oldest epoch led to the same item being
evicted over and over, leading to blocking of over 5 minutes in extreme
cases where alternate epochs/shuffling got loaded repeatedly.
Changing the cache eviction strategy to least-recently-used seems to
improve the situation drastically. A simple implementation was selected
based on single linked-list without a hashtable.

When the BN's head is reorged while shut down, reloading the BN will not
assign `BlockRef` to alternate branches. However, blocks from other
branches are still present in the database, leading to their descendants
incorrectly marked as `UnviableFork`. By restricting the check to blocks
that have been finalized, they should be reported as `MissingParent`
instead, eventually re-assigning a `BlockRef` to them.

accelerate EL sync with LC with `--sync-light-client` (#4041)
When the BN-embedded LC makes sync progress, pass the corresponding
execution block hash to the EL via `engine_forkchoiceUpdatedV1`.
This allows the EL to sync to wall slot while the chain DAG is behind.
Renamed `--light-client` to `--sync-light-client` for clarity, and
`--light-client-trusted-block-root` to `--trusted-block-root` for
consistency with `nimbus_light_client`.

Note that this does not work well in practice at this time:
- Geth sticks to the optimistic sync:
  "Ignoring payload while snap syncing" (when passing the LC head)
  "Forkchoice requested unknown head" (when updating to LC head)
- Nethermind syncs to LC head but does not report ancestors as VALID,
  so the main forward sync is still stuck in optimistic mode:
  "Pre-pivot block, ignored and returned Syncing"

To aid EL client teams in fixing those issues, having this available
as a hidden option is still useful.

reduce LC optsync latency (#4002)
The optimistic sync spec was updated since the LC based optsync module
was introduced. It is no longer necessary to wait for the justified
checkpoint to have execution enabled; instead, any block is okay to be
optimistically imported to the EL client, as long as its parent block
has execution enabled. Complex syncing logic has been removed, and the
LC optsync module will now follow gossip directly, reducing the latency
when using this module. Note that because this is now based on gossip
instead of using sync manager / request manager, that individual blocks
may be missed. However, EL clients should recover from this by fetching
missing blocks themselves.

cache shuffling separately from other EpochRef data (fixes #2677) (#3990)
In order to avoid full replays when validating attestations hailing from
untaken forks, it's better to keep shufflings separate from `EpochRef`
and perform a lookahead on the shuffling when processing the block that
determines them.

This also helps performance in the case where REST clients are trying to
perform lookahead on attestation duties and decreases memory usage by
sharing shufflings between EpochRef instances of the same dependent
root.
