BREAKING(unstable): remove WebGPU (#18094)

This PR _**temporarily**_ removes WebGPU (which has behind the
`--unstable` flag in Deno), due to performance complications due to its
presence.

It will be brought back in the future; as a point of reference, Chrome
will ship WebGPU to stable on 26/04/2023.

-## wgpu_sync.js

-`wgpu_sync.js` streamlines updating `deno_webgpu` from
-[gfx-rs/wgpu](https://github.com/gfx-rs/wgpu/).
-
-It essentially vendors the `deno_webgpu` tree with a few minor patches applied
-on top, somewhat similar to `git subtree`.
-
-1. Update `COMMIT` or `V_WGPU` in `./tools/wgpu_sync.js`
-2. Run `./tools/wgpu_sync.js`
-3. Double check changes, possibly patch
-4. Commit & send a PR with the updates
