Looks like one test is failing, I'll investigate that.

A couple updates:

• The CI in Dawn's upstream repository (https://github.com/google/dawn/actions/workflows/ci.yml) have been failing for a few weeks now, which causes issues for the CI here since it was relying on pulling their artifacts. So I created my own release of Dawn with the binaries from the last successful build here: https://github.com/reeselevine/dawn/releases/tag/v1.0.0, and am using that in the WebGPU CI here now.
• I'm not 100% sure why the WebGPU Ubuntu CI test was failing in earlier commits on this PR, as I could not reproduce it locally. My best guess is that there was something broken in the interaction between Dawn's thread-safe implementation (which they call ImplicitDeviceSynchronization) and the simulated LLVMpipe Vulkan backend used by the CI here. Right now, it seems like combining the successful build from the previous Dawn commits and the updated code in this PR is stable, the CI runs successfully locally and has succeeded in a few successive commits.

Going forward, I'll roll my own releases of Dawn when necessary, and once the Dawn folks are able to get their CI working again. Otherwise the code here is ready for review/merging.

@CISC @ggerganov

@reeselevine It looks like the CI is stalling after a crash due to missing SET_ROWS support.

@CISC yeah I noticed that after it was merged 😞. Simplest solution is to disable set rows for now, I have a commit ready: reeselevine@ae8edbf

But I also am working on adding support for SET_ROWS. If I get that done today I'll open a PR with support for it, otherwise I'll open a quick PR with that fix.
