[fuzz] Validate IR modules against fuzzer-specific capabilities

Different IR fuzzers have different predconditions and therefore
require the IR module to be validated against different IR
capabilities. Add a parameter to the TINT_IR_MODULE_FUZZER macro that
fuzzers use to set their supported capabilities.

Instead of validating the IR module once after decoding, move
validation into the Run loop so that we can validate against these
per-fuzzer capabilities.

Move capability lists to transform header files so that they can be
shared between fuzzers and the transforms themselves.

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.
