reduce `nim-eth` dependencies just for RNG (#5099)
We have several modules that import `nim-eth` for the sole purpose of
its `keys.newRng` function. This function is meanwhile a simple wrapper
around `nim-bearssl`'s `HmacDrbgContext.new()`, so the import doesn't
really serve a use anymore. Replace `keys.newRng` with the direct call
to reduce `nim-eth` imports.

Add Deneb beacon API types (#5060)
* Add Deneb beacon API types

- Introduce the `ProduceBlockResponseV2` type for handling responses to `GET /eth/v2/validator/blocks/{slot}` (https://ethereum.github.io/beacon-APIs/?urls.primaryName=dev#/Validator/produceBlockV2)

- Introduce the `RestPublishedSignedBlockContents` type for handling the request body to `POST /eth/v1/beacon/blocks` (https://ethereum.github.io/beacon-APIs/?urls.primaryName=dev#/ValidatorRequiredApi/publishBlock)

And a few other small changes towards Deneb block production support.

Fix sync for blocks older than MIN_EPOCHS_FOR_BLOB_SIDECARS_REQUESTS (#4977)
When doing sync for blocks older than
MIN_EPOCHS_FOR_BLOB_SIDECARS_REQUESTS, we skip the blobs by range
request, but we then pass en empty blob sequence to
validation, which then fails.

To fix this: Use an Option[Blobsidecars] to allow expressing the
distinction between "empty blob sequence" and "blobs unavailable". Use
the latter for "old" blocks, and don't attempt to run blob validation.

segregate sync committee messages by period / fork (#4953)
`SyncCommitteeMsgPool` grouped messages by their `beacon_block_root`.
This is problematic around sync committee period boundaries and forks.
Around sync committee period boundaries, members from both the current
and next sync committee may sign the same `beacon_block_root`; mixing
the signatures from both committees together is a mistake. Likewise,
around fork transitions, the `signing_root` changes, so those messages
also need to be segregated.

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.

eip4844 beacon block proposals (#4540)
* eip4844 beacon block proposals

* Don't fetch blobs under minimal preset

@tersec's summary of the issue:

BlobsBundleV1 in the execution API spec assumes a mainnet preset blob
size, where the EIP4844 consensus spec defines
FIELD_ELEMENTS_PER_BLOB: 4 under the minimal preset, which leads to a
Blob having a length of 4 * 32, not 4096 * 32 which BlobsBundleV1
requires.

* Revert unintentional script change
