* eth/catalyst: allow payload attributes v1 in fcu v2 (ethereum#28882)

At some point, `ForkchoiceUpdatedV2` stopped working for `PayloadAttributesV1` while `paris` was active. This was causing a few failures in hive. This PR fixes that, and also adds a gate in `ForkchoiceUpdatedV1` to disallow `PayloadAttributesV3`.
