Refactor DungeonEditor and introduce new components for enhanced dungeon editing

- Integrated new components: DungeonToolset, DungeonObjectInteraction, DungeonRenderer, DungeonRoomLoader, and DungeonUsageTracker to streamline dungeon editing functionalities.
- Updated DungeonEditor to utilize the new components for room loading, object interaction, and rendering, improving code organization and maintainability.
- Enhanced object selection and placement features, including drag-and-drop functionality and improved UI interactions.
- Removed legacy methods and refactored existing code to delegate responsibilities to the new components, ensuring a cleaner architecture.
- Added support for usage tracking of blocksets, spritesets, and palettes across dungeon rooms, providing insights for optimization.
