qmp, hmp: add PCI subsystem id and vendor id to PCI info
This is a long story. Red Hat has relicensed Windows KVM device drivers
in 2018 and there was an agreement that to avoid WHQL driver conflict
software manufacturers should set proper PCI subsystem vendor ID in
their distributions. Thus PCI subsystem vendor id becomes actively used.
The problem is that this field is applied by us via hardware compats.
Thus technically it could be lost.
This patch adds PCI susbsystem id and vendor id to exportable parameters
for validation.
