[tint][ir] Refactor Instruction result methods

Remove HasResults() and HasMultiResults(). These are virtual functions,
and are usually followed up with another virtual call to Result() or
Results(). This pattern is expensive and so should be discouraged.

Add an index to Operand() and Result() to keep these accessors
symmetrical.

Replace the Args() virtual methods with a virtual ArgsOperandOffset().
When we split methods into const and non-const flavors, this reduces the
number of duplicated methods as we can implement a const and non-const
Args() in the base class.

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.
