feat(ext/http): Add `addr` to HttpServer (#23442)

Adds an `addr` field to `HttpServer` to simplify the pattern
`Deno.serve({ onListen({ port } => listenPort = port })`. This becomes:
`const server = Deno.serve({}); port = server.addr.port`.

Changes:
- Refactors `serve` overloads to split TLS out (in preparation for
landing a place for the TLS SNI information)
- Adds an `addr` field to `HttpServer` that matches the `addr` field of
the corresponding `Deno.Listener`s.
