[hlsl] Support 8-bit subgroup matrix scalar builtins

Upcast the matrix to a 32-bit component type before applying the
operation, since HLSL does not natively support 8-bit integers.

This requires that the same matrix geometries are also supported with
32-bit types, which requires filtering out linalg configurations that
do not satisfy this constraint. This will be done in a future CL.

Remove the 8-bit overloads of Get/Set from hlsl.def since they do not
exist.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
