Add performance monitoring capabilities with PerformanceMonitor class

Browse Source 
- Introduced PerformanceMonitor and ScopedTimer classes for tracking operation durations, enhancing performance analysis during ROM loading and rendering.
- Integrated performance monitoring into the OverworldEditor and Overworld classes, allowing for detailed timing of critical operations.
- Implemented deferred texture creation strategies to optimize loading times and reduce main thread blocking.
- Updated relevant methods to utilize performance monitoring, providing insights into loading efficiency and potential bottlenecks.
