MDEV-25629: Crash in get_sort_by_table() in subquery with order by having outer ref
In Item_field::fix_fields(): when the item was resolved to an Item_field
in the SELECT's select_list, copy the Item_field's "depended_from" field.
Failure to do so caused the item to have incorrect attributes: it pointed
to a Field in an upper select but used_tables() didn't return
OUTER_REF_TABLE_BIT.
