MDEV-13774: Server Crash on Execute of SQL Statement
Window functions can not be used as arguments to aggregate functions, as
the aggregation happens before window function computation. Disallow
such constructs by returning an error.
In order to detect this case a change was needed in the base
Item_sum_xxx::fix_fields to propagate the with_window_func flag.
Item_func_group_concat requires the same change.
