Part of #23494.
datafusion/datasource/src/memory.rs. DataSource::try_to_proto for the MemoryScan variant; record-batch IPC serde is pure Arrow (inline locally). Blocked by #23497.
Follow the pattern in #23494 (reference impl: #23495 / ProjectionExec; full end-state draft: #23496). Add try_to_proto inside impl ExecutionPlan for X, add the inherent X::try_from_proto, repoint the decode arm, and delete the old central arm in the same PR (that is the proof the hook is reached). Keep the wire format byte-for-byte identical.
