Refactor CMake configuration for core library and testing

- Updated CMakeLists.txt to create a separate core library (yaze_core) for testing, enhancing modularity.
- Adjusted source file organization for yaze_c and yaze_core, ensuring proper inclusion of essential components.
- Modified test CMakeLists.txt to link against yaze_core instead of yaze_c, streamlining dependencies for test targets.
- Disabled installation of the library in minimal builds while maintaining the ability to build for testing purposes.
