[ir] Add Instruction::DetachResult() helper

This removes an instruction result from an instruction and returns
it. This makes it easier to move an instruction result to a new
instruction, which should be more efficient than using
`ReplaceAllUsesWith()` to update usages one at a time.

Add overloads of a few IR Builder functions that take an
InstructionResult so that the IR builder can be used with this
pattern, instead of manually creating instructions with the allocator.

Update many transforms to use this pattern.

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.
