vfio: Add property documentation

Browse source 
Investigate the git history to uncover when and why the VFIO
properties were introduced and update the models. This is mostly
targeting vfio-pci device, since vfio-platform, vfio-ap and vfio-ccw
devices are simpler.

Sort the properties based on the QEMU version in which they were
introduced.
