Add feature capability indication for P802.11az security for the drivers
to advertise capabilities such as secure LTF support, secure RTT
measurement exchange support, and protection of range negotiation and
measurement management frames for station and AP interfaces
independently. This allows a more fine-tuned capability indication as an
alternative to the upstream nl80211 mechanism that is not specific to
the operating mode.
