feat(unstable): remove Deno.upgradeHttp API (#21856)

Closes https://github.com/denoland/deno/issues/21828.

This API is a huge footgun. And given that "Deno.serveHttp" is a
deprecated API that is discouraged to use (use "Deno.serve()" 
instead); it makes no sense to keep this API around.

This is a step towards fully migrating to Hyper 1.
