Enhance graphics editor performance with batch processing and profiling

- Integrated performance profiling using ScopedTimer in GraphicsEditor and ScreenEditor for better timing insights.
- Implemented batch texture updates in GraphicsEditor and ScreenEditor to reduce individual texture update calls, improving rendering efficiency.
- Enhanced tile rendering in ScreenEditor with pre-allocated vectors for batch operations, optimizing drawing performance.
- Added safety checks and validation in various components to prevent crashes and ensure data integrity during rendering operations.
- Updated Bitmap and Arena classes to support improved texture management and synchronization, enhancing overall graphics performance.
