John Guo 5cbe421aaa feat(contrib/drivers): more database drivers (#4553 )

This pull request adds first-class support for MariaDB, TiDB, OceanBase,
and GaussDB as separate database drivers in the GoFrame ecosystem,
rather than relying solely on MySQL compatibility. It introduces new
driver packages for each database, updates documentation to reflect
these additions, and adjusts dependency management files accordingly.
The changes also deprecate the MariaDB-specific logic in the MySQL
driver in favor of the new dedicated MariaDB driver.

**New Database Driver Support**

* Added new driver packages for MariaDB, TiDB, OceanBase, and GaussDB
under `contrib/drivers/`, each with their own Go module files and driver
implementation that wraps the MySQL driver for protocol compatibility
and future extensibility.

* Registered these new drivers in the main module's `go.mod` and
`go.work` files for proper dependency resolution and local development.

**Documentation Updates**

* Expanded the `contrib/drivers/README.MD` to include installation and
import instructions for the new drivers, and clarified the supported
drivers section with dedicated code examples for each.

**MariaDB Driver Enhancements**

* Implemented a MariaDB-specific `TableFields` method and SQL query in
the new driver, improving the accuracy of table field retrieval for
MariaDB databases.
* Added unit test initialization code for MariaDB to ensure driver
functionality.

**Deprecation and Refactoring**

* Marked the MariaDB-specific logic and SQL in the MySQL driver as
deprecated, with a note to remove it in the next version, directing
users to the new MariaDB driver instead.
