Requests execution payload envelope by `signed_execution_payload_envelope.message.block_root`. The response is a list of `SignedExecutionPayloadEnvelope` whose length is less than or equal to the number of requested execution payload envelopes. It may be less in the case that the responding peer is missing payload envelopes.

ExecutionPayloadEnvelopeByRoot is primarily used to recover recent execution payload envelope (e.g. when receiving a payload attestation with revealed status as true but never received a payload).
ExecutionPayloadEnvelopesByRoot is primarily used to recover recent execution payload envelopes (e.g. when receiving a payload attestation with revealed status as true but never received a payload).
The request MUST be encoded as an SSZ-field.
