vfio-pci: Provide reviewers and acceptance criteria for variant drivers

Device specific extensions for devices exposed to userspace through
the vfio-pci-core library open both new functionality and new risks.
Here we attempt to provided formalized requirements and expectations
to ensure that future drivers both collaborate in their interaction
with existing host drivers, as well as receive additional reviews
from community members with experience in this area.
