Pectra Engine API Validation

[siladu]

One known issue with engine_newPayload: we don't invalidate when V4 data (executionRequests) is sent to engine_newPayloadV3, we only validate if V4 data is missing from engine_newPayloadV4.

Spec says: https://github.com/ethereum/execution-apis/blob/main/src/engine/cancun.md#engine_newpayloadv3

Client software MUST check that provided set of parameters and their fields strictly matches the expected one and return -32602: Invalid params error if this check fails.

I expect this error would show up in the hive tests, see #8177

Also check against spec for other inconsistencies.

Maybe need to run the cancun hive tests to check this?

newPayloadV3 containing V4's executionRequests incorrectly responds with VALID...
