Reland "Use Swiftshader by default when fuzzing"

This is a reland of d08a14b70982a90423f4965ae5625847316de09e

It gates dawn_use_swiftshader on dawn_enable_vulkan because the
Vulkan backend isn't supported on Mac. We may support Swiftshader
Vulkan on Mac in the future, but that will first require changes
to how we initialize the Vulkan backend.

Original change's description:
> Use Swiftshader by default when fuzzing
>
> Note: This still requires Chromium to have set dawn_swiftshader_dir
> to take effect.
>

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 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
