Refactor logging system to use LOG_* macros

- Updated logging calls in main.cc, rom.cc, and test_manager.cc to utilize the new LOG_* macros for consistency and improved readability.
- Removed deprecated util::logf function and replaced its usage with appropriate logging macros.
- Enhanced logging in TestManager to provide more detailed information about ROM state and testing processes.
- Cleaned up commented-out logf calls in room.cc to streamline the code.
- Adjusted LogManager to support general logging through a new logf function for non-category specific messages.
