MDEV-24454 Crash at change_item_treebb-10.2-MDEV-24454
Use in_sum_func (and so nest_level) only in LEX to which SELECT lex belong to
Reduce usage of current_select (because it does not always point on the correct
SELECT_LEX, for example with prepare.
Change context for all classes inherited from Item_ident (was only for Item_field) in case of pushing down it to HAVING.
Now name resolution context have to have SELECT_LEX reference if the context is present.
Fixed feedback plugin stack usage.
