feat: Enhance emulator UI and performance features

- Added new UI components for the emulator, including dedicated panels for CPU and APU debugging, improving user interaction and debugging capabilities.
- Implemented a caching mechanism for rendered objects in the DungeonCanvasViewer to optimize performance and reduce rendering time.
- Updated the CMake configuration to include new UI source files, ensuring proper organization and build management.
- Enhanced the theme manager with improved color definitions for better visibility and consistency across the UI.
- Refactored the emulator interface to delegate rendering tasks to the UI layer, streamlining the codebase and improving maintainability.
