Add commands to find out which commands does each group support, as well as enable their use by driver. This will be especially useful once we have multiple group types. An alternative is per-type VQs. This is possible but will require more per-transport work. Discovery through the vq helps keep things contained. e.g. lack of support for some command can switch to a legacy mode note that commands are expected to be avolved by adding new fields to command specific data at the tail, so we generally do not need feature bits for compatibility.
