When no EL is connected, it is still required to validate the block hash
of `ExecutionPayload` to prevent attacks that trick us into attesting to
a circular chain with invalid in-between block hashes. This is already
done through Deneb but was still missing in Electra to be rectified now.
* bump nim-eth to `d8fda55c79dd48ba564f3cb540b968f4a1c1aae6`
- Overhaul of ENR implementation - part I
- Rework of ENR decoding code
- Update discv5 to use non deprecated ENR calls and simplify code
- simplify .nimble file
- avoid warnings when processing `GasInt` for RLP
- define Electra types and RLP encoding
* explicitly indicate consensus types over nim-eth types in EL manager
Bump nim-blscurve, nim-faststreams, nim-http-utils, nim-metrics,
nim-presto, nim-serialization, nim-snappy for explicit refc and use
`results` instead of `stew/results`.
* extend light client protocol for Electra
Add missing Electra support for light client protocol:
- https://github.com/ethereum/consensus-specs/pull/3811
Tested against PR consensus-spec-tests, the test runner automatically
picks up the new tests once available.
* workaround `version-2-0`: `Error: cannot instantiate: 'SomeUnsignedInt'`
* fix initialization when Electra not scheduled
* try reduce stack size in test
* put correct sync committee branch version into DB
* adjust fork schedule in light client data tests
* further reduce stack size
* split function into multiple parts
* rename variable
* regenerate test reports to cover new Electra tests
* add Nim bug reference
* bump nimbus-build-system to use Nim v2.0.6
* fix: update name and hash for csources of Nim v2
Otherwise we get errors like:
```

```
Also need to add source for `checksums` repository.

Including sync contributions into a block affects validator rewards.
When we have not received aggregate sync contributions, but have seen
individual messages, we can produce the contributions locally, improving
validator rewards when subscribing to all subnets or when having a
non-aggregating attached validator in the sync committee.
Addresses two inaccuracies in light client data size documentation:
1. `SyncCommittee` pubkeys serialize are 48 bytes not 64 bytes
2. Some of the estimates used 1000 vs 1024 bytes/KB, aligned to 1024
