chore(cmake): link test support conditionally for yaze and yaze_emu

- Added conditional linkage of the yaze_test_support library for both yaze and yaze_emu targets when tests are enabled, ensuring proper integration with TestManager.
- This change enhances the modularity of the CMake configuration by managing test dependencies more effectively.

Benefits:
- Improved organization of test support linkage in the CMake configuration.
- Enhanced maintainability by ensuring that test dependencies are only included when necessary.
