Improve QuickExit so that the normal exit process also has the speed of Alt+F4

[DeathFishAtEase]

Our QuickExit already implements fast exit via Alt+F4, but exiting through the normal settings page process is still as slow and painfully unpleasant as before, so I made this.

Not quite sure if I missed any design considerations; feedback is welcome.

@DeathFishAtEase What about Exit and Destruct events in multiplayer?

[DeathFishAtEase]

Neither event is lost. Both Destruct and Exit are broadcast to the peer by the per-frame Send_Packets step before our hook ever runs; the hook only skips the local EVA-voice wait, it does not touch any network signaling.
