Holocene: use extraData instead of nonce for eip-1559 parameters

[roberto-bayardo]

Description

Use extraData for holocene EIP-1559 parameters so it will be propagated along with the execution payload.

Additional context

Corresponding spec update: ethereum-optimism/specs#428

Definitely most simple to just pass through the encoded params vs having them in a more human readable form. In theory, if there is an update to the serialization, we would be able to use hardfork branching to modify the way they are deserialized

Looks good to me

I'm going to change this to use ExecutionPayloadEnvelope as discussed on the call.

Turned out to not be a great solution. Latest plan is to move from nonce to extradata for the params. extraData is already in the execution payload, so it simplifies things a lot. Plus we probably want to use Nonce for sub-second block increments later on.

Looks good. Can you update the fork.yaml to describe the changes to the files (also including some prior changes of e.g. introducing EIP1559Params to the payload attributes type)?

yes. ok to do that in another PR? Want to get this in to unblock the op-node reviews
