[tools][cts roll] Rework tag reduction

The following changes attempt to fix issues where result tags can be a subset of another. This is a long-standing issue that causes incorrect expectation updates.

Split cleanupTags() into removeUnknownTags() and RemoveLowerPriorityTags().

removeUnknownTags() is run before tree folding and redundant tag set removal.

RemoveLowerPriorityTags() is now done after tree folding and redundant tag set removal.
This is has to be done later to avoid ambiguities with tag sets which are not mutually exclusive.
More details of the issues being addressed can be found in https://crbug.com/1498681.

An example of the new tag output can be seen in https://dawn-review.googlesource.com/c/dawn/+/159202

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.
