feat: fully remove Deno.serveHttp API

[bartlomieju]

While technically a breaking change, this API has been soft-deprecated since Deno 1.46 and
hard deprecated in Deno 2 - there are no type declarations nor documentation for this API.

I want to give it a go and remove it for the Deno 3 RC releases and see the impact.

I suggest doing the same for Deno.run, Deno.stderr.rid, Deno.stdin.rid, Deno.stdout.rid and Deno.isatty.
