Part of #23494.
joins/cross_join.rs, joins/nested_loop_join.rs. Two children; NLJ adds JoinType (by-name match), optional JoinFilter, and the [u32::MAX] empty-projection sentinel. See HashJoinExec in #23496 as the join template.
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.
