Use MYSQL_TYPE constants instead of FIELD_TYPE

The FIELD_TYPE constants are for BC. The JSON/VECTOR types are not
defined in FIELD_TYPE for libmysqlclient.
MYSQL_TYPE is available since MYSQL 5.0.0, so switch to that.

Since MYSQL_TYPEs are enums and not defines, we need version checks
instead.
JSON was added in mysql 8.0.0 in mysql/mysql-server@c24045514581
JSON support was backported via mysql/mysql-server@3e14f9f in 5.7.8.
VECTOR was added in mysql 9.0.0 in mysql/mysql-server@8cd51511de7d

Replaces phpGH-20245.
