feat: enhance CMake configuration for conditional AI test inclusion

- Updated CMakeLists.txt to conditionally include AI GUI controller tests and experimental AI test suites based on the YAZE_ENABLE_AI_RUNTIME flag.
- Added status messages to inform users when AI tests are skipped due to the runtime being disabled, improving clarity in the build process.
- This change ensures that tests related to AI features are only compiled and run when the appropriate runtime is enabled, enhancing modularity and build efficiency.
