feat: add Low GPU Accuracy setting for maximum performance

Implements a new "Low" GPU accuracy level that prioritizes performance
over accuracy by aggressively cutting corners in GPU emulation.

Changes:
- Add GpuAccuracy::Low enum and setting infrastructure
- Implement IsGPULevelNormal() helper function
- Skip texture cache checks and query operations
- Use unsafe memory reads for DMA operations
- Disable fence delays and query precision
- Add UI support for desktop (Qt) and Android

Performance optimizations:
- Skips texture cache coherency checks (vk/gl_rasterizer.cpp)
- Non-blocking query synchronization (query_cache.h)
- Unsafe memory operations (dma_pusher.cpp)
- No macro parameter refresh (maxwell_3d.cpp)
- Immediate fence signaling (fence_manager.h)
- Non-precise Vulkan queries (vk_query_cache.cpp)

Ideal for lower-end hardware and users prioritizing FPS over accuracy.
Works on both desktop and Android platforms.
