This pull request introduces a new database driver for openGauss
(GaussDB), integrating it into the GoFrame framework. The implementation
includes connection handling, SQL execution, type conversion, and other
driver-specific logic. Additionally, the CI workflow is updated to
include an openGauss server for testing. The main themes are: new driver
implementation, SQL and type handling, and CI integration.
**GaussDB Driver Implementation:**
* Added a new driver in `contrib/drivers/gaussdb` to support
openGauss/GaussDB databases, including initialization, connection
handling, and registration with GoFrame's database abstraction.
(`gaussdb.go`, `gaussdb_open.go`)

* Implemented custom SQL execution and result handling to support
GaussDB's PostgreSQL-based features, including primary key handling on
insert and custom result types. (`gaussdb_do_exec.go`,
`gaussdb_result.go`)

**SQL and Type Handling:**
* Added SQL filtering and placeholder conversion to support
PostgreSQL-style parameterization and GaussDB-specific SQL quirks, such
as handling `INSERT IGNORE` and JSONB syntax. (`gaussdb_do_filter.go`)
* Implemented comprehensive type conversion logic for mapping
PostgreSQL/GaussDB types to Go types, including arrays, UUIDs, and
custom handling for JSON and numeric types. (`gaussdb_convert.go`)
* Provided a function for random ordering (`ORDER BY RANDOM()`) and
explicitly disabled upsert/ON CONFLICT support, as GaussDB does not
support this feature. (`gaussdb_order.go`, `gaussdb_format_upsert.go`)

**CI Integration:**
* Updated the CI workflow to start an openGauss server in Docker,
enabling automated tests against the new driver.

This pull request introduces significant improvements to the handling of
the `Replace` and `Save` operations for multiple database drivers,
especially for MSSQL and PostgreSQL. The changes ensure that these
operations now auto-detect primary keys when conflict columns are not
explicitly provided, improving usability and aligning behavior across
drivers. Additionally, the pull request updates related tests to reflect
these enhancements and includes some minor documentation and code
cleanup.
**Key changes:**
### Enhanced Replace/Save Logic for Database Drivers
* **MSSQL Driver:**
- `Replace` and `Save` operations now auto-detect primary keys if
`OnConflict` is not specified, using the `MERGE` statement for upsert
functionality. If no primary key is found in the data, a detailed error
is returned.

- Updated tests to verify that `Replace` correctly updates or inserts
records, and that missing conflict columns are properly handled.

* **PostgreSQL Driver:**
- Similar to MSSQL, `Replace` and `Save` now auto-detect primary keys
for conflict resolution if `OnConflict` is not set, and treat `Replace`
as a `Save` operation.
- Adjusted tests to ensure `Save` and `Replace` work as expected,
including verifying data replacement and insertion.

* **DM Driver:**
- Improved conflict detection: now checks that at least one primary key
exists in the provided data when `OnConflict` is not specified, and
provides clearer error messages.
- Refactored to use the core method for primary key detection and
removed redundant code.
### Minor Improvements and Documentation
* Added clarifying comments to `DoInsert` methods for ClickHouse, DM,
MSSQL, Oracle, and PostgreSQL drivers, specifying that the input list
must have at least one validated record.
