feat: Add Application Entry Point for Yaze

- Introduced app_main.cc as the main entry point for the Yaze application, separating it from the C API implementation.
- Implemented command-line flag parsing for ROM file loading, logging level, log file path, and log categories.
- Configured the logging system to enhance traceability and user feedback during application startup and execution.
- Integrated the core controller for managing application state and rendering, improving overall application structure and functionality.
