[dawn][webgpu.h] Remove webgpu_cpp.h's use of memcpy.

This use was added for a temporary workaround of const char* in
callbacks instead of wgpu::StringView. The addition of the memcpy should
have come with a corresponding #include <cstring> but instead replace
the memcpy with a manually written loop. This is ok because 1) the code
is cold and the deprecated path and 2) compilers know to replace such
simple loops with memcpy calls. This way in the future when the
deprecation workaround is removed, we don't need to remember to remove
the #include.

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.
