further reduce stack size of LC helpers for Nim 2.0 (#5401)
The `is_next_sync_committee_known` helper allocates a fresh
`SyncCommittee` in the caller and `nimZeroMem`s it on each use.
Use `static` to compare against a compile-time zeroed copy instead.
This also should help reduce stack size far enough to link with Nim 2.0.

It is useful to verify transactions data against `transactionsRoot`.

reduce memory allocations during state transition (#5235)
This PR removes a few hundred thousand temporary seq allocations during
state transition - in particular, the flag seq was allocated per
validator while committees are computed per attestation.

accelerate `getShufflingRef` (#4911)
When an uncached `ShufflingRef` is requested, we currently replay state
which can take several seconds. Acceleration is possible by:

1. Start from any state with locked-in `get_active_validator_indices`.
   Any blocks / slots applied to such a state can only affect that
   result for future epochs, so are viable for querying target epoch.
   `compute_activation_exit_epoch(state.slot.epoch) > target.epoch`

2. Determine highest common ancestor among `state` and `target.blck`.
   At the ancestor slot, same rules re `get_active_validator_indices`.
   `compute_activation_exit_epoch(ancestorSlot.epoch) > target.epoch`

3. We now have a `state` that shares history with `target.blck` up
   through a common ancestor slot. Any blocks / slots that the `state`
   contains, which are not part of the `target.blck` history, affect
   `get_active_validator_indices` at epochs _after_ `target.epoch`.

4. Select `state.randao_mixes[N]` that is closest to common ancestor.
   Either direction is fine (above / below ancestor).

5. From that RANDAO mix, mix in / out all RANDAO reveals from blocks
   in-between. This is just an XOR operation, so fully reversible.
   `mix = mix xor SHA256(blck.message.body.randao_reveal)`

6. Compute the attester dependent slot from `target.epoch`.
   `if epoch >= 2: (target.epoch - 1).start_slot - 1 else: GENESIS_SLOT`

7. Trace back from `target.blck` to the attester dependent slot.
   We now have the destination for which we want to obtain RANDAO.

8. Mix in all RANDAO reveals from blocks up through the `dependentBlck`.
   Same method, no special handling necessary for epoch transitions.

9. Combine `get_active_validator_indices` from `state` at `target.epoch`
   with the recovered RANDAO value at `dependentBlck` to obtain the
   requested shuffling, and construct the `ShufflingRef` without replay.

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

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.

add `LightClientHeader` wrapper (#4481)
The light client data structures were changed to accommodate additional
fields in future forks (e.g., to also hold execution data).

There is a minor change to the JSON serialization, where the `header`
properties are now nested inside a `LightClientHeader`.
The SSZ serialization remains compatible.
