wpa_supplicant AP: Add preliminary support for WPS Internal Registrar

When in AP mode, wpa_supplicant is now enabling WPS (only Internal
Registrar). wpa_cli wps_pbc and wps_pin commands can be used to initiate
WPS negotiation similarly to how this is done in station mode (though,
the BSSID parameter is ignored).
