[github] Use CMake to fetch deps in Emdawnwebgpu release jobs

Replace (most of) the custom dependency fetching in
package-emdawnwebgpu.sh in favor of DAWN_FETCH_DEPENDENCIES (which also
does a shallow fetch). Fetching the other dependencies surprisingly only
took an extra 22 seconds when tested on GitHub Actions, and it will be
needed if we start publishing prebuilt native binaries anyway.

This should fix the release jobs on GitHub Actions which currently fail
due to a missing Tint dependency on protobuf. (We don't actually need to
build Tint on that job, but we don't have a CMake option to disable
building Tint, and we don't need one if we just fetch all the deps.)

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.
