primitive_id -> primitive_index

Update the name of the primitive_id feature to primitive_index based on
final name decided on by the working group. The old
chromium-experimental-primitive-id feature is kept around temporarily to
assist in rolling into Chrome but should be removed soon as it's
unlikely that any Dawn users have begun using this version of the
feature.

Using No-Presubmit to avoid a bug with Tint presubmit checks and
renaming a symbol. See https://issues.chromium.org/u/1/issues/440321534

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.
