seat: Rework seat activation/switch logic

Browse source 
The seat activation logic did not correctly handle VT switching and
switching between multiple sessions.

Session switching on VT-bound seats is now performed using a VT switch,
taking advantage of VT signals to perform the actual switch. This
simplifies switching logic and makes it more robust.
