#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.
Fix the `/eth/v1/beacon/deposit_snapshot` API to produce proper EIP-4881
compatible `DepositTreeSnapshot` responses. The endpoint used to expose
a Nimbus-specific database internal format.
Also fix trusted node sync to consume properly formatted EIP-4881 data
with `--with-deposit-snapshot`, and `--finalized-deposit-tree-snapshot`
beacon node launch option to use the EIP-4881 data. Further ensure that
`ncli_testnet` produces EIP-4881 formatted data for interoperability.
* 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`.

Fix regression from #5842 where `Eth-Execution-Payload-Value` is parsed
into `consensusValue` instead of `Eth-consensus-Block-Value`. We don't
use those values for now, but fixing avoids hard-to-debug bugs later.
This PR allows sharing the pubkey data between validators by using a
thread-local cache for pubkey data, netting about a 400mb mem usage
reduction on holesky due to us keeping 3 permanent + several ephemeral
state copies in memory at all times and each state copy holding a full
validator.
The PR also introduces a hash cache for the key which gives ~14% speedup
for a full state `hash_tree_root` - the key makes up for a large part of
the `Validator` htr time.
Finally, the time it takes to copy a state goes down as well from ~80m
ms to ~60, for reasons similar to htr.
We use a `ptr` even if a `ref` could in theory have been used - there is
not much practical benefit to a `ref` (given it's mutable) while a `ptr`
is cheaper and easier to copy (when copying temporary states).
We could go further and cache a cooked pubkey but it turns out this is
quite intrusive - in all the relevant places, we're already using a
cooked key from the immutable validator data so there are no immediate
performance gains of doing so while managing the compressed -> cooked
key mapping would become more difficult - something for a future PR
perhaps.

Changes here are more significant because of some good old tech debt in
block production which has grown quite hairy - the reduction in
exception handling at least provides some steps in the right direction.
* Avoid global in p2p macro (fixes#4578)
* copy p2p macro to this repo and start de-crufting it
* make protocol registration dynamic, removing light client hacks et al
* split out light client protocol into its own file
* cleanups
* Option -> Opt
* remove more cruft
* further split beacon_sync
this allows the light client to respond to peer metadata messages
without exposing the block sync protocol
* better protocol init
* "constant" protocol index
* avoid casts
* copyright
* move some discovery code to discovery
* avoid extraneous data copy when sending chunks
* remove redundant forkdigest field
* document how to connect to a specific peer
With Capella, `bls_to_execution_change` SSE should be emitted on the
event stream whenever a new `SignedBLSToExecutionChange` is received.
Add this missing functionality for compatibility with beacon-API specs.

This requires all object types to be explicitly white-listed for
default serialization. The PR makes the minimal changes, although
a number of similar mechanisms in eth2_rest_serialization can now
be removed.
