Co-Authored-By: Rodrigo Locatti <reinuseslisp@airmail.cc>

* fix LayeredFS error when loading some games made with the Unity

 video_core: Use native ASTC when available 

shader_decompiler: Remove FragCoord.w hack and change IPA implementation

gl_rasterizer: Mark cleared textures as dirty

This updates to the latest available toolchain for MSVC builds.

configuration: Reorder shoulder buttons

services: ldr: Fix MemoryState for read/write regions of NROs.

shader/memory: Silence no return value warning

Silences a warning about control paths not all returning a value.

Refactor Context management (Fixes renderdoc on opengl issues)

Credits go to gdkchan and Ryujinx. The pull request used for this can
be found here: https://github.com/Ryujinx/Ryujinx/pull/1082

yuzu was already using the header for interpolation, but it was missing
the FragCoord.w multiplication described in the linked pull request.
This commit finally removes the FragCoord.w == 1.0f hack from the shader
decompiler.

While we are at it, this commit renames some enumerations to match
Nvidia's documentation (linked below) and fixes component declaration
order in the shader program header (z and w were swapped).
