MonitorManager: add a KMS backend
Using the new Cogl API to actually modeset (because we can't use the DRM API directly without controlling buffer swap), we can finally have a KMS monitor backend, which means full display configuration when running on bare metal. https://bugzilla.gnome.org/show_bug.cgi?id=706308
