Current cte common filter extraction doesn't work if the filters can be aggregated, which will lead the common filter can't be pushed down inside cte. Consider the following case:
with main as (select c1 from t1) select * from (select m1.* from main m1, main m2 where m1.c1 = m2.c1) abc where c1 = 1;
The common c1=1 filter can't be pushed down.
This pr fixed the original extraction logic from set to list to make the logic works, and this will also resolve the tpcds query4/11's pattern works well also.
