Improve performance of queries with correlated subqueries in IDAA v7 - another

This request for enhancement is related to queries with correlated sub-queries that IDAAs V7 don't have capacity to solve.

Accordingly with IBM support it will be necessary that: remove correlated predicates that do not have reference of columns/expressions from the subquery and add it parent operator above. Unfortunately, there is no internal rewrite to do that automatically.

This request is a result of performance issues which described in case TS010049651
