Added support for instance-level PCI NUMA policies using the
``hw:pci_numa_affinity_policy`` flavor extra spec and
``hw_pci_numa_affinity_policy`` image metadata property.
These apply to both PCI passthrough and SR-IOV devices,
unlike host-level PCI NUMA policies configured via the
``alias`` key of the ``[pci] alias`` config option.
See the `VM Scoped SR-IOV NUMA Affinity`_ spec for more
info.
