Un-break whole-row Vars referencing domain-over-composite types. In commit ec62cb0aa, I foolishly replaced ExecEvalWholeRowVar's lookup_rowtype_tupdesc_domain call with just lookup_rowtype_tupdesc, because I didn't see how a domain could be involved there, and there were no regression test cases to jog my memory. But the existing code was correct, so revert that change and add a test case showing why it's necessary. (Note: per comment in struct DatumTupleFields, it is correct to produce an output tuple that's labeled with the base composite type, not the domain; hence just blindly looking through the domain is correct here.)
Per bug #17515 from Dan Kubb. Back-patch to v11 where domains over composites became a thing.
