Enhance CMake configuration and CI/CD workflows for improved testing

- Updated CMakeLists.txt to introduce options for enabling experimental tests and minimal CI builds.
- Modified CMakePresets.json to refine test presets, including stable and experimental test configurations.
- Enhanced CI workflows in ci.yml to streamline testing processes, ensuring stable tests are prioritized and experimental tests are run separately.
- Added new documentation files outlining the CI/CD testing strategy and testing categories for better clarity on testing practices.
- Improved test discovery in CMakeLists.txt to simplify labeling and enhance CI efficiency.
