[wgslfuzz] Validate against IR fuzzer preconditions

When wrapping an IR fuzzer with a WGSL fuzzer, we should validate
against the IR fuzzer precondition capabilities before running the
fuzzer function.

We should also not consider these validation failures to be bugs, as
they are only signalling an issue with AST->IR or substitute
overrides, both of which have their own IR fuzzers. This change is
necessary in order to validate against the preconditions as described
above.

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.
