[fuzz] Handle sidecar data in assembler/disassembler

When converting a tint_wgsl_fuzzer test case to a .tirb file, if there
is a leading comment with configuration data, populate the output
.tirb' data section with it. And when converting a tint_ir_fuzzer test
case to a .wgsl file, if there is bytes in a .data, write out an
equivalent leading comment.

test/tint/fuzzing_coverage_test.wgsl is updated to be in format that
the tint CLI emits, so that one can do things like ir_fuzz_as ->
ir_fuzz_dis -> diff to test roundtripping manually.

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.
