Alexander Barkov 30903c3743 MDEV-22976 CAST(JSON_EXTRACT() AS DECIMAL) does not handle boolean values ...

Item_func_json_extract did not implement val_decimal(),
so CAST(JSON_EXTRACT('{"x":true}', '$.x') AS DECIMAL) erroneously
returned 0 with a warning because of convertion from the string "true"
to decimal.

Implementing val_decimal(), so boolean values are correctly handled.
