MDEV-16722: Assertion `type() != NULL_ITEM' failed
We hit this assert during the create of a temporary table field
because the current code does not handle the case when the value
of the NAME_CONST function is NULL.
Fixed this by allowing creation of temporary table fields even
for the case when NAME_CONST returns NULL value.
Introduced tmp_table_field_from_field_type_maybe_null() function
in Item class so both Item_basic_value and Item_name_const can use it.
Introduced a virtual method get_func_item() in the Item class.
