Simplify CMake workflow by removing redundancies

- Consolidated 6 jobs into 3 jobs for better maintainability
- Removed duplicate CMake version testing, integration tests, and build configurations
- Maintained all essential test coverage while reducing CI runtime
- Simplified matrix configuration with explicit generator values for all entries
