Refactor the network link dialogs

* Unifies the network link options into a single dialog by removing the
  separate dialog for the timeout option.
* Cleans up the logic related to starting the network link.
* Moves more options to g_owned_opts.
* Separates the server and client port into 2 separate options.

Test: Locally with Mario Kart with 2 instances.
