[tint][ir][val] Cleanup up how expectations are handled

Convert to using substring matching for error strings, instead of
matching the entire output. This removes all of the notes/disassembly
in the expectations, significantly shortening the test files.

If we want whole validation log testing, this should be done via
something like the end to end tests, i.e. having pairs of input files
(IR proto probably) and expected output files that are run outside of
the unit test framework.

For tests where there are multiple errors in the current string, if
they are incidental to what is being tested then they are just removed
from testing, and if there is multiple conditions being tested in one
case there are multiple EXPECTs. A future CL will break up these
multiple EXPECT cases into separate or parameterized tests.

The failure reason is piped into the matcher macros, so that when they
are violated the entire text is still printed out in the test log for
debugging.

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.
