* electra attestation updates
In Electra, we have two attestation formats: on-chain and on-network -
the former combines all committees of a slot in a single committee bit
list.
This PR makes a number of cleanups to move towards fixing this -
attestation packing however still needs to be fixed as it currently
creates attestations with a single committee only which is very
inefficient.

Using a dedicated branch for researching the effectiveness of split view
scenario handling simplifies testing and avoids having partial work on
`unstable`. If we want, we can reintroduce it under a `--debug` flag at
a later time. But for now, Goerli is a rare opoprtunity to test this,
maybe just for another week or so.

In split view situation, the canonical chain may only be served by a
tiny amount of peers, and branches may span long durations. Minority
branches may still have a large weight from attestations and should
be discovered. To assist with that, add a branch discovery module that
assists in such a situation by specifically targeting peers with unknown
histories and downloading from them, in addition to sync manager work
which handles popular branches.
There are situations where all states in the `blockchain_dag` are
occupied and cannot be borrowed.
- headState: Many assumptions in the code that it cannot be advanced
- clearanceState: Resets every time a new block gets imported, including
blocks from non-canonical branches
- epochRefState: Used even more frequently than clearanceState
This means that during the catch-up mechanic where the head state is
slowly advanced to wall clock to catch up on validator duties in the
situation where the canonical head is way behind non-canonical heads,
we cannot use any of the three existing states. In that situation,
Nimbus already consumes an increased amount of memory due to all the
`BlockRef`, fork choice states and so on, so experience is degraded.
It seems reasonable to allocate a fourth state temporarily during that
mechanic, until a new proposal could be made on the canonical chain.
Note that currently, on `unstable`, proposals _do_ happen every couple
hours because sync manager doesn't manage to discover additional heads
in a split-view scenario on Goerli. However, with the branch discovery
module, new blocks are discovered all the time, and the clearanceState
may no longer be borrowed as it is reset to different branch too often.
The extra state could also find other uses in the future, e.g., for
incremental computations as in reindexing the database, or online
collection of historical light client data.
During lag spike, e.g., from state replays, peer count can temporarily
drop significantly. Should not have to wait another 60 minutes in that
situation just to be back where one started.
Nimbus currently stops performing validator duties if the blockchain
does not progress for `node.config.syncHorizon` slots. This means that
the chain won't recover because no new blocks are proposed. To fix that,
continue performing validator duties if no progress is registered for a
long time, and none of our peers is indicating any progress.
#6087 introduced a subtle change to `nim-web3` resulting in `Gwei` to be
serialized differently than before. Using a `distinct` type for `Gwei`
improves type safety and avoids such problems in the future.

* add EIP-7044 support to keymanager API
When trying to sign `VoluntaryExit` via keymanager API, the logic is not
yet aware of EIP-7044 (part of Deneb). This patch adds missing EIP-7044
support to the keymanager API as well.
As part of this, the VC needs to become aware about:
- `CAPELLA_FORK_VERSION`: To correctly form the EIP-7044 signing domain.
The fork schedule does not indicate which of the results, if any,
corresponds to Capella.
- `CAPELLA_FORK_EPOCH`: To detect whether Capella was scheduled.
If a BN does not have it in its config while other BNs have it,
this leads to a log if Capella has not activated yet, or marks the BN
as incompatible if Capella already activated.
- `DENEB_FORK_EPOCH`: To check whether EIP-7044 logic should be used.
Related PRs:
- #5120 added support for processing EIP-7044 `VoluntaryExit` messages
as part of the state transition functions (tested by EF spec tests).
- #5953 synced the support from #5120 to gossip validation.
- #5954 added support to the `nimbus_beacon_node deposits exit` command.
- #5956 contains an alternative generic version of `VCForkConfig`.
