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.
