feat: Add FSR 2.0 scaling filter option

- Add FSR2 to ScalingFilter enum alongside existing FSR
- Implement FSR2 classes for both Vulkan and OpenGL renderers
- Add fsr2_quality_mode setting with 4 quality levels (Quality, Balanced, Performance, Ultra Performance)
- Integrate FSR2 into present pipeline for both renderers
- Add UI support for FSR2 option in scaling filter dropdown
- Add FSR2 quality mode setting with dropdown selection
- Update translations and Android strings for new options
- Default to Performance mode for optimal balance

This provides users with FSR 2.0 as a scaling option, offering different
quality/performance characteristics compared to FSR 1.0. The implementation
uses quality-based sharpening values and integrates seamlessly with the
existing rendering pipeline.
