Refactor logging and tracing in SDL3 application

- Replaced macro-based logging with a dedicated Logger class for improved readability and maintainability.
- Introduced TraceGuard class for automatic function entry/exit logging.
- Updated all relevant source files to utilize the new logging and tracing mechanisms.
- Consolidated SDL_MAIN_HANDLED definition into a separate header file (sdl_macros.hpp) for better organization.
- Ensured consistent logging practices across the application, including error handling and debug information.
