monitor-manager-dummy: Add way to emulate tiled monitors
By setting the environment variable MUTTER_DEBUG_TILED_DUMMY_MONITORS to "1", the dummy MetaMonitorManager backend used when running mutter nested will create tiled monitors instead of single-output/CRTC monitors. This makes it possible to test tiled monitor configuration. https://bugzilla.gnome.org/show_bug.cgi?id=779745
