Enhance performance profiling and tile caching mechanisms

Browse Source 
- Introduced a new PerformanceProfiler class for detailed timing and performance measurement across graphics operations.
- Implemented a smart tile cache with LRU eviction in the TileCache structure to optimize memory usage and improve tile rendering efficiency.
- Updated various graphics components to utilize the new caching system, reducing redundant texture updates and enhancing overall performance.
- Added dirty region tracking in Bitmap for efficient texture updates, minimizing the area that needs to be refreshed during rendering.
- Enhanced existing methods to leverage performance monitoring, providing insights into operation durations and potential bottlenecks.
