[tint] Implement subgroupElect and BroadcastFirst

Implement subgroupElect and subgroupBroadcastFirst builtins for WGSL,
SPIR-V IR backend (not AST), MSL AST and IR backends and HLSL AST and IR backends. Subgroup builtins are not yet implemented for the GLSL
backend.

Also implement subgroupBroadcast for the MSL IR backend where was not
yet supported.

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.
