vhost: Add VhostShadowVirtqueue
Vhost shadow virtqueue (SVQ) is an intermediate jump for virtqueue
notifications and buffers, allowing qemu to track them. While qemu is
forwarding the buffers and virtqueue changes, it is able to commit the
memory it's being dirtied, the same way regular qemu's VirtIO devices
do.
This commit only exposes basic SVQ allocation and free. Next patches of
the series add functionality like notifications and buffers forwarding.
