[ASTERIXDB-2611][*DB] Fix GroupAll with empty input

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

Details:
This patch is to fix the issue with group by all where
some partitions are empty. The patch in general handles
propagating outer scope variables through group by all by using
subplans instead of using decor variables when translating
the AST.

- changed IsomorphismVariableMappingVisitor to stop re-visiting
  the same nested tuple operator pair again
- moved getFdColumns() up in hierarchy to be shared by others
- added a check to prevent group-all with decoration fields
