GPortalNotificationBackend: Implement it's own serialization method

Browse Source 
The portal and GTK notifications will diverge, since they follow
different specs. For now it wasn't a problem since the portal was
strongly limited and essentially the same as the org.gtk.Notifications
interface. The serialization code is mostly the same as the already existing
serialization code.
