Marco Trevisan (Treviño) f231672084 monitor: Add support to privacy screen
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.
