[emscripten][github] Include a "remote" emdawnwebgpu port in the release

Thanks to https://github.com/emscripten-core/emscripten/pull/24303
(which should be in the next Emscription release, 4.0.10), users can use
this new port format which just includes a pointer to a zip containing a
port file.

This change generates and releases a port file like the one used in
Emscripten, which can (1) be used instead of extracting the zip and (2)
be copied directly into Emscripten whenever we want to update its
version of `tools/ports/emdawnwebgpu.py`. It includes a full copy of the
package README as a docstring to make the port self-documenting.

Our version of Emscripten is still 4.0.8, but people can use this with
4.0.10+.

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.
