Update CMake configuration to enhance test suite management

- Modified `CMakeLists.txt` to cache the `YAZE_BUILD_TESTS` option, improving clarity in test suite configuration.
- Updated the GitHub Actions workflow to include verification steps for the CMake configuration, ensuring that test targets are correctly identified.
- Adjusted test discovery logic in `test/CMakeLists.txt` to double-check that tests are enabled, enhancing the robustness of the build process.
