libqmi-glib,device: new method to check support for link management

We need a way to know whether we can do link management before
attempting to add a new link, because the whole connection logic will
depend on whether we can create those new links or not (e.g. we would
need to bind mux data port and enable QMAP aggregation before creating
the new link)
