[ir] Move type member to Value base class

All but one subclass of Value declared its own type member and
SetType() method, as well as overriding the virtual Type()
getter. Instead, just declare the type in the base class and define
those methods in the base class too.

As well as removing an unnecessary virtual method and duplicated code
in the subclasses, this also makes it possible to call SetType() on a
value without first casting it to a subclass, which is used to
slightly simplify a callsite in ChangeImmediateToUniform.

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.
