instead of adding this method, shall we just call executeQuery in executeCollect?

…ProjectExec This PR fixes a bug when there are subqueries in `TakeOrderedAndProjectExec`. The executeCollect method does not wait for subqueries to finish and it can result in IllegalArgumentException when executing a simple query. For example this query: ``` WITH t2 AS ( SELECT * FROM t1 ORDER BY id ) SELECT *, (SELECT COUNT(*) FROM t2) FROM t2 LIMIT 10 ``` will fail with this error ``` java.lang.IllegalArgumentException: requirement failed: Subquery subquery#242, [id=#109] has not finished ``` To fix a bug. No New unit test No Closes#43419 from allisonwang-db/spark-45584-subquery-failure.
