Integrate performance monitoring across various editors

- Added performance monitoring capabilities using ScopedTimer in the DungeonEditor, PaletteEditor, ScreenEditor, MessageEditor, MusicEditor, SpriteEditor, and SettingsEditor classes to track loading times.
- Enhanced the Load methods in each editor to include timing for critical operations, improving performance analysis and optimization.
- Removed unnecessary debug output in the Sprite class to clean up the codebase.
