vfio/pci: Add virtual capabilities quirk infrastructure

Browse source 
If the hypervisor needs to add purely virtual capabilties, give us a
hook through quirks to do that.  Note that we determine the maximum
size for a capability based on the physical device, if we insert a
virtual capability, that can change.  Therefore if maximum size is
smaller after added virt capabilities, use that.
