gdk_display_list_devices is deprecated and all the backends implement the same fallback by delegating to the device manager and caching the list (caching it is needed since the method does not transfer ownership of the container). The compat code can be shared among all backends and we can initialize the list lazily only in the case someone calls the deprecated method. https://bugzilla.gnome.org/show_bug.cgi?id=762891
