Productionise Withdrawals Engine API Changes

[siladu]

Full implementation of https://github.com/ethereum/execution-apis/blob/main/src/engine/shanghai.md

The WIP is rather large and hard to review: https://github.com/hyperledger/besu/pull/4552

Ideally this should be split into PRs to get this into main behind the shanghaiTimestamp fork.

~Therefore this story is blocked on the shanghaiTimestamp PR.~

Note, this is strongly related to https://github.com/hyperledger/besu/issues/4777 and it might make sense to do unit tests and refactor per PR split.

One suggested split is:

• ~EVM logic - WithdrawalsProcessor~ Covered by #4878
• Supporting new withdrawals and withdrawalsRoot fields in domain layer, most wiring.
• API EngineForkchoiceUpdatedV2, EngineNewPayloadV2, EngineGetPayloadV2, etc
  • There is also a small piece of validation to add for engine_newPayloadV2 (null/non-null withdrawals when pre/post-shanghai)
