The flatpak notification portal reads permissions out
of the permission store, so forward the notification
permissions there in order to prevent sandboxed
applications from sending notifications.
The difference is a bit cosmetic, since the shell would
not show the notification anyway in this case, but it
is nicer to just cut off the calls and not let them
through the portal in the first place.

Show applications using the message tray, and
allow configuring in what way the shell presents them.
The set of applications shown include all applications that ever
showed a notification in gnome-shell and all applications that have
a boolean X-GNOME-UsesNotifications key set to true in their desktop file.
