NotificationManager: use GIO instead of libportal
GIO's notification implementation makes the code more readable and has the advantage of supporting multiple notification specifications. By default we will now use freedesktop notifications when running without `.desktop` file and XDG-portal notifications when running with `.desktop` file. To prevent dynamic notification updates from arriving in wrong order at the desktop environment, we need to manually queue them up and make sure that there is at least 200ms delay between updates.
