nested: Allow configuration of dummy output configuration
Enable a user to test and debug multi output configurations on Wayland without having the available hardware by enabling some basic configuration of the dummy monitor manager. Currently available configuration options are: MUTTER_DEBUG_NUM_DUMMY_MONITORS - to set the number of monitors MUTTER_DEBUG_DUMMY_MONITOR_SCALES - to configure the monitor scales See src/backends/meta-monitor-manager-dummy.c for detailed description of the available configuration parameters. https://bugzilla.gnome.org/show_bug.cgi?id=747089
