backend/drm: Add support for hotplug_mode_update connector property

Browse source 
This connector property is used by virtual graphics drivers to indicate
that a virtual display has changed its list of supported resolutions and
updated its preferred mode. In the event of a hotplug the connector is
considered to be "re-plugged" without disconnecting first. This allows
virtual displays to be resized automatically when their window size
changes.
