[tools][cts] Make tags less explicit

Changes how the CTS roller generates expectations for failing tests.
Previously, the most explicit tags were used. Now, the least explicit
tags from several core tag sets (OS, GPU, device) are used. The old
behavior is still available behind the --generate-explicit-tags flag.

This is almost guaranteed to generate expectations which are overly
broad, but the unexpected pass finder will be used to automatically
narrow expectations to the configurations that actually need them.

This CL also includes the following changes to the expectation files:
  * Auto-generated expectations have their tags simplified in accordance
    with the CTS roller changes
  * Skip expectations moved into permanent/temporary Skip expectations
    to make it clearer which should be fixed vs. left alone
  * Old CTS roller annotations removed since the simplified code path
    is here to stay

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.
