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

texture: Implement R32I

texture_cache: Implement layered framebuffer attachments

vk_shader_decompiler: Implement Layer output attribute

surface_base: Implement texture buffer flushes

Kernel: Refactors and Implement a TimeManager and SchedulerLocks

audio_core: interpolate: Fix include for climits (Linux build break).

audio_core: Switch to a faster interpolation technique

shader/texture: Fix illegal 3D texture assert

Fix typo in the illegal 3D texture assert logic. We care about catching
arrayed 3D textures or 3D shadow textures, not regular 3D textures.

renderer_vulkan: Add the rest of case for TryConvertBorderColor

vk_shader: Implement ImageLoad

vulkan: add DXT23_SRGB

texture_cache: Avoid matches in 3D textures

video_core: memory_manager: Flush/invalidate asynchronously when possible.

Update httplib to 0.5.5

shader/texture: Allow 2D shadow arrays and simplify code

- Minor perf improvement.

maxwell_3d: Unify draw methods
