[dawn] Remove usage of std::string_view in favor of absl::string_view

- Although in most cases, absl::string_view is just an alias for
  std::string_view, when using some of the absl string utilities,
  i.e. StrSplit or StrJoin on platforms that don't do the aliasing,
  compilation will fail.
- This was seen in google3 Emscripten builds which currently don't
  do the type aliasing resulting in incompatible conversions.
- Note that the google3 standard at the moment is to continue using
  absl::string_view and rely on the aliasing (when available) even
  though technically std::string_view is available.

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.
