vfio/iommufd: cpr state
VFIO iommufd devices will need access to ioas_id, devid, and hwpt_id in
new QEMU at realize time, so add them to CPR state. Define CprVFIODevice
as the object which holds the state and is serialized to the vmstate file.
Define accessors to copy state between VFIODevice and CprVFIODevice.
