* add withdrawalsRoot to ExecutionPayload. * add a `BlocksV4` topic to p2p gossip and check for non-empty withdrawalsRoot on v4 topic. * add checks for whether block is type v4 and apply relevant marshal/unmarshal for l2 withdrawals root.
* attributes check * outputV0AtBlock api update * minor type updates
and fixes for a few failures
when computing L2OutputRoot, no need to re-compute the storage root if Isthmus is active.
and fix lint errors
* `RPCResponseCheck` is an interface that currently has a function that validates withdrawals. * There's an implementation of this interface for L1 and L2 * L1's response checker validates that the withdrawals list matches the root in the header. * L2's response checker validates that the withdrawals list is empty when the withdrawalsRoot is not nil
will move to a separate PR
