screenShield: Show detailed notification data if notifications hint it
Allow notifications to set a x-gnome-privacy-scope hint, with values in ['system', 'user']. If all the notifications in a particular source hint that their privacy scope is ‘system’, don’t hide the notification details on the lock screen.
This is aimed at fixing the particular case of power notifications: they contain information which is not private to the user (it relates to the system: battery state or AC state, which is obvious to anyone who can see the machine), so hiding the details of a power management notification when the screen is locked is pointless.
