vk_shader_decompiler: Implement indexed textures

shader_decode: Fix LD, LDG when track constant buffer

Refactoring to boot A32 games

video_core: Implement more scaled attribute formats

ARM_Interface: Cache the JITs instead of deleting/recreating.

Port citra-emu/citra#5097: "Update README.md"

audio_core: interpolate: Improvements to fix audio crackling.

renderer_opengl: Fix SRGB presentation frame tracking.

- Fixes SRGB in Super Smash Bros. Ultimate.

It fixed opcode LD, LDG on Pokemon Sword that can't find the constant buffer. Not sure if it helps any on visual.

This was a bug inherited from citra which was fixed by then at some 
time. This commit corrects such bug and ensures JITs are correctly 
recycled.

shader: implement LOP3 fast replace for old function

InputCommon: analog_from_button get direction implementation

video_core/surface: Add R32_SINT render target format

video_core/gpu: Remove unused functions
