[emscripten] Fix fillAdapterInfoStruct__deps & externs

The deps need to be on the fillAdapterInfoStruct helper rather than the
functions that use it, I think because it's positioned like a public API
so Emscripten assumes it can't eliminate it (but still assumes it can
eliminate stringToNewUTF8). It's not an immediate code size problem
because Closure still eliminates it if it's unused, but Closure needs
the code to be valid to do that.

Tested this fixes a local release+closure build.

Also updated the externs for these; I have not verified that change (but
it's safe, it can't break anything).

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.
