console: rework text terminal cursor logic
Have a global timer. Update all visible terminal windows syncronously. Right now this can be the active_console only, but that will change soon. The global timer will disable itself if not needed, so we only have to care start it if needed. Which might be at console switch time or when a new displaychangelistener is registered.
