- 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.

Fix LTO linking issues on CachyOS with GCC 15.x
- Add LTO support to all core library targets (input_common, frontend_common,
network, shader_recompiler, web_service) that were missing LTO configuration
- Create citron_configure_lto() helper function for consistent LTO handling
- Implement CachyOS-specific detection via /etc/os-release and kernel version
- Apply conservative LTO flags (-flto=auto -ffat-lto-objects) only for
CachyOS + GCC 15+ to resolve linking errors with newer toolchains
- Other distributions continue using aggressive LTO settings for maximum performance
- Disable LTO on executable targets to prevent main function optimization issues
This resolves "undefined symbol" errors when building with -DCITRON_ENABLE_LTO=ON
on CachyOS while maintaining optimal LTO performance on other distributions.
Fixes linking errors including:
- Core::Frontend::EmuWindow symbols
- Core::System methods
- Settings::values
- Common logging functions
Tested on CachyOS with GCC 15.1.1 + LLD 20.1.8

Persistent buffer maps were already used by the texture cache, this extends their usage for the buffer cache.
In my testing, using the memory maps for uploads was slower than the existing "ImmediateUpload" path, so the memory map usage is limited to downloads for the time being.
