MDEV-8865 Wrong field type or metadata for COALESCE(signed_int_column, unsigned_int_column)
Item_func_hybrid_field_type did not return correct field_type(), cmp_type()
and result_type() in some cases, because cached_result_type and
cached_field_type were set in independent pieces of the code and
did not properly match to each other.
Fix:
- Removing Item_func_hybrid_result_type
- Deriving Item_func_hybrid_field_type directly from Item_func
- Introducing a new class Type_handler which guarantees that
field_type(), cmp_type() and result_type() are always properly synchronized
and using the new class in Item_func_hybrid_field_type.
