Add secure HE-LTF protocol version to capabilities

The secure HE-LTF negotiation supports negotiation of the secure HE-LTF
protocol version. IEEE 802.11az secure ranging initiator can either
proceed with responders protocol version assignment. If it does not
meet the required security level, initiator can terminate the ranging.

Secure ranging result gives the protocol version used. Add a new
parameter to get the maximum supported secure HE-LTF protocol version by
the initiator.
