Port several small multiplayer PRs from yuzu (#7419)

* yuzu: Use displayed port on direct connect

* Color player counts in the multiplayer public lobby list

- Full lobbies have their player count displayed in red.
- Lobbies with one slot left have their player count displayed in orange.
- Empty lobbies have their player count grayed out.

* Add hotkeys for multiplayer actions

Default shortcuts were chosen as to be intuitive (use the first letter
of the action, or the second word's first letter) and work on all
types of keyboards. The hotkeys can be used while playing a game too,
as they are application-wide.

* Persist filters in multiplayer public lobby list

After connecting to a room, the chosen filter text, "Games I Own",
"Hide Empty Rooms" and "Hide Full Rooms" values are persisted
to configuration so they are preserved across restarts.

This makes it easier to rejoin a room if you regularly play the same
game, or after a crash.
