feat: Implement modular build system for Yaze

- Added option to enable modular build with `YAZE_USE_MODULAR_BUILD`.
- Updated CMake configuration to support modular libraries for core, editor, graphics, GUI, and emulator functionalities.
- Refactored existing libraries to separate concerns and improve build times.
- Introduced new utility library `yaze_util` for low-level utilities.
- Adjusted CI and release workflows to accommodate the new build system.
- Updated various source files to reflect new include paths and modular structure.
- Enhanced YAML configuration handling in the agent component.
