qapi: add '@fdset' feature for BlockdevOptionsVirtioBlkVhostVdpa
The virtio-blk-vhost-vdpa driver in libblkio 1.3.0 supports the fd
passing through the new 'fd' property.
Since now we are using qemu_open() on '@path' if the virtio-blk driver
supports the fd passing, let's announce it.
In this way, the management layer can pass the file descriptor of an
already opened vhost-vdpa character device. This is useful especially
when the device can only be accessed with certain privileges.
Add the '@fdset' feature only when the virtio-blk-vhost-vdpa driver
in libblkio supports it.
