Extension that want to expose their own preferences (for example as menu
items) do that by passing their UUID to gnome-shell-extension-prefs.
But since 3.36.1 the app is optional and no longer accepts arguments on
the command line. To adjust, extensions now need to make a D-Bus call
the extensions portal, just like the app and gnome-shell.
We will add a convenience method for that purpose, so it makes
sense to share the existing code. As it's extension-related, the
extension manager looks like the right place ...
