VIRTIO_RING_F_EVENT_IDX is a virtio feature that allows to avoid device <-> driver notifications under some circunstances, most notably when actively polling the queue. This commit implements support for in in the vm-virtio crate. Consumers of this crate will also need to add support for it by exposing the feature and calling using update_avail_event() and get_used_event() accordingly.
