netlink/specs: Add VF attributes to rt_link spec 



Add support for retrieving VFs as part of link info. For example:

./tools/net/ynl/cli.py --spec Documentation/netlink/specs/rt_link.yaml \
  --do getlink --json '{"ifi-index": 38, "ext-mask": ["vf", "skip-stats"]}'
{'address': 'b6:75:91:f2:64:65',
 [snip]
 'vfinfo-list': {'info': [{'broadcast': b'\xff\xff\xff\xff\xff\xff\x00\x00'
