Remove clipboard functionality and enhance performance monitoring features
- Deleted clipboard-related files (clipboard.cc, clipboard.h, clipboard.mm) to streamline the codebase. - Added a performance dashboard in the EditorManager to monitor performance metrics and improve user experience. - Integrated performance monitoring capabilities across various editors, allowing for detailed timing of critical operations. - Updated the graphics system with batch processing for texture updates, significantly improving rendering performance. - Introduced a memory pool allocator for efficient memory management during graphics operations.
