[ir] Update `Value` parameters.

This CL updates the various instructions to allow the provided `Value`s
to be `nullptr`. These will be checked by the validator to ensure they
do not move through to the backends.

The `AddOperand` and `AddOperands` methods are updated to take the
operand position. The provided position is then validated against
the operand list to validate that it is the next appended item. This
verifies that the operands are added at the expected indices so any call
to `SetOperand` will work as expected.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress 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.
