MDEV-15296: wrong result with window function inside a subquery10.2-wf
Window Functions were treated as a constant in a dependent tables less subquery.
Made sure that the behaviour of window functions is same as the aggregate function
for dependent tables less subquery.
Also propagted Item::with_window_func for few missing cases.
