Add TWT responder support for AP in HT and VHT modes

Browse source 
Add support for TWT responder for AP operating in HT and VHT modes by
introducing a new configuration parameter ht_vht_twt_responder. When
this is enabled, TWT responder mode support in HT and VHT modes is
enabled if the driver supports this and is disabled otherwise.
