[Feature] Add wrapper structs for stateless APIs

[syjn99]

Component

rpc

Describe the feature you would like

I'm implementing engine_executeStatelessPayloadVX APIs(Issue#12766, PR#13016), found that rpc-types-engine should support some wrapper structs for this API. Here's the candidates, please do not hesitate if there are better options for those:

• ExecutionPayloadWithWitnessV{1,2,3}: contains payload_inner and execution_witness(similar to the struct ExecutionWitness at go-ethereum)
  • NOTE: this struct will be used as an input value for engine_newPayloadWithWitnessV{1,2,3,4} and engine_executeStatelessPayloadV{1,2,3,4}.
• StatelessPayloadStatus: contains status, state_root, receipts_root and latest_valid_hash.
  • NOTE: this struct will be used as an output value for engine_executeStatelessPayloadV{1,2,3,4}

I'm glad to take this issue for my first contribution to alloy. Thank you
