feat: Add frame generation and enhance UE4 game compatibility

Browse Source 
- Add frame generation settings (enabled/disabled, interpolation/extrapolation modes)
- Add frame skipping settings (enabled/disabled, adaptive/fixed modes)
- Implement frame skipping logic with adaptive and fixed modes
- Enhance UE4 crash handling with recovery mechanisms
- Add support for signed and float 32-bit image formats across shader backends
- Update Vulkan Validation Layers to v1.4.321.0
- Fix duplicate frame skipping options in Qt UI
- Improve memory handling for UE4 games (Hogwarts Legacy compatibility)
- Add enhanced bindless texture handling with fallback approach
- Update Android build configuration and dependencies
