MDEV-24093: Detect during mysql_upgrade if type_mysql_json.so is needed and load it

a. The change makes `mariadb-upgrade` detect if `MYSQL_JSON` data type is needed.
b. Install the data type if it's not installed.
c. Uninstalls the data type once finished.
d. Create `.opt` and `.inc` files `have_type_mysql_json` and adapt the
tests
