refactor: Update Emulator Command-Line Flags and CMake Configuration

Browse Source 
- Renamed command-line flags for improved clarity and consistency, enhancing usability for ROM loading, GUI options, and state management.
- Adjusted default maximum frames for emulator execution to 180, optimizing performance settings.
- Refactored CMake configuration to reflect changes in source file structure, ensuring proper build setup for the emulator application.
