MDEV-9634: Window function produces incorrect value
- Item_sum_count::remove() should check if the argument's value is NULL.
- Window Function item must have its Item_window_func::split_sum_func
called,
- and it must call split_sum_func for aggregate's arguments (see the
comment near Item_window_func::split_sum_func for explanation why)
