fix: deny unknown payload fields

[Rjected]

A hive test would send an excessBlobGas field to our engine_newPayloadV2 endpoint, and the test expected us to return the Invalid params code and error.

This adds deny_unknown_fields to payload types, and adds tests that make sure unknown fields are rejected.

This causes the pyspec cancun/eip4844_blobs/excess_blob_gas_fork_transition/invalid_pre_fork_block_with_blob_fields/000-fork=ShanghaiToCancunAtTime15k-excess_blob_gas_present=True-blob_gas_used_present=False-invalid_pre_fork_blob_fields test to succeed.
