Reland "[dawn][emscripten][test] Add workaround for WASM tests startup."

This reverts commit 4a0c46b153c71a058820536bef5c5b9eb681f162.

Reason for revert: Re-reverting this because in google3, the version of chromium used for testing is currently 135.0.7049.52, but the version where the fix for this went in was 136.0.7085.0. We need to wait a bit longer before we can fully remove this workaround. (We are seeing flakes in the test again atm)

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.
