I tracked it down using git blame, they were added initially for the Deposit functionality of Ethereum but I believe signature verification was later moved to the CL, if it was ever in the EL at some stage.
Right now we only get the RLP, validate that the fields are there and use them to compute the requests hash, nothing else. Look at DepositLogDecoder.
So we don't need these classes anymore.

I feel like this could bite at runtime.

IMO this will be optimized out, specially if we never trip it. If there's a way it doesn't we should make it easier for the compiler to do so.

PR description
This PR is a follow-up cleanup of PR #9556 to remove unnecessary
Bytes32usages where appropriate. I've observed that choice betweenBytes32andHashin code is not always appropriate so this helps clarify some parts of the code where we really meanHashand notBytes32.Both are 32 bytes in size, in reality
Hashis actually a keccak256 hashing function value which always outputs 32 byte.Other cleanups will follow but I cut this work here to make it reviewable.
