Reland "[dawn][webgpu.h] Use wgpu::StringView for strings in output structs."

This is a reland of commit 980e48de901e70a01ca96fcc30032492bfc1468f

Original change's description:
> [dawn][webgpu.h] Use wgpu::StringView for strings in output structs.
>
> These are wgpu::AdapterInfo and wgpu::CompilationMessage.
>
>  - Adds a deprecation #define for a few code changes in Skia and
>    Chromium.
>  - Fixup the FreeMembers logic for StringView that 1) doesn't need a
>    FreeMembers method itself, 2) should have .data checked when deciding
>    whether to auto-free members in the C++ header.
>  - For convenience, add StringView support to webgpu_cpp_print.h
>  - During conversion of dawn::native, try to simplify the handling of
>    allocation and returning of output strings in Adapter and
>    CompilationMessages.
>  - Likewise for dawn::wire.
>  - Simplify GPUCompilationMessages in dawn.node to compute all members
>    in its constructor.
>  - Fixup various other files for compilation errors after the change.

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.
