Adds a fast path for ExecutionPayloadEnvelope and BlobAndProofListV* that bypasses encoding/json's reflection and re-validation, which are expensive for large payloads with many blobs. Also hand-rolls the jsonrpcMessage wire encoding in the RPC codec to avoid a second re-validation pass when writing responses to the connection. Resolves #33814 --------- Co-authored-by: Marius van der Wijden <m.vanderwijden@live.de> Co-authored-by: Felix Lange <fjl@twurst.com>
