qemu: caps: Introduce capability for 'device_id' property of 'scsi-disk'

The property allows to control the guest-visible content of the vendor
specific designator of the 'Device Identification' page of a SCSI
device's VPD (vital product data).

QEMU was leaking the id string of -drive as the value if the 'serial' of
the disk was not specified. Switching to -blockdev would impose an ABI
change.
