Eugenio Pérez 8c5e980922 vdpa: add VhostVDPAShared
It will hold properties shared among all vhost_vdpa instances associated
with of the same device.  For example, we just need one iova_tree or one
memory listener for the entire device.

Next patches will register the vhost_vdpa memory listener at the
beginning of the VM migration at the destination. This enables QEMU to
map the memory to the device before stopping the VM at the source,
instead of doing while both source and destination are stopped, thus
minimizing the downtime.

However, the destination QEMU is unaware of which vhost_vdpa struct will
register its memory_listener.  If the source guest has CVQ enabled, it
will be the one associated with the CVQ.  Otherwise, it will be the
first one.

Save the memory operations related members in a common place rather than
always in the first / last vhost_vdpa.
