cfg80211: implement APIs for dedicated radar detection HW
If a dedicated (off-channel) radar detection hardware (chain) is available in the hardware/driver, allow this to be used by calling the NL80211_CMD_RADAR_DETECT command with a new flag attribute requesting off-channel radar detection is used. Offchannel CAC (channel availability check) avoids the CAC downtime when switching to a radar channel or when turning on the AP. Drivers advertise support for this using the new feature flag NL80211_EXT_FEATURE_RADAR_OFFCHAN.
