MDEV-31599: Assertion `0' failed in Item_param::can_return_value

Browse Source 
from Item::val_json, UBSAN: member access within null pointer of
type 'struct String' in sql/item_jsonfunc.cc

Analysis:
The first argument of json_schema_valid() needs to be a constant.
Fix:
Parse the schema if the item is constant otherwise set it to return null.
