Some monitors support hardware features to enable the privacy screen mode that allows users to toggle (via software or hardware button) a state in which the display may be harder to see to people not sitting in front of it. Expose then this capability to the monitor level so that we can get its state and set it. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1952>
