[RFC 07/34] wpa_supplicant: Add control interface commands for NAN

[Andrei Otcheretianski]

From: Ilan Peer <ilan.peer at intel.com>

- Add control interface commands to start/stop NAN operation. All
  the NAN commands should be handled only on the control interface
  associated with the NAN Device interface.
- Add indication for NAN support when querying for capabilities.
