[ASTERIXDB-2837][COMP] Improve subplan consolidation

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
- Improve EliminateIsomorphicSubplanRule so it can

- Improve PushAggFuncIntoStandaloneAggregateRule and
  PushAggregateIntoNestedSubplanRule so they can handle
  aggregate operators with multiple output variables
