nl80211: add HT/VHT capabilities to AP parameters

For the benefit of drivers that rebuild IEs in firmware, parse the
IEs for HT/VHT capabilities and the respective membership selector
in the (extended) supported rates. This avoids duplicating the same
code into all drivers that need this information.
