cfg80211: Allow TDLS peer AID to be configured for VHT

VHT uses peer AID in the PARTIAL_AID field in TDLS frames. The current
design for TDLS is to first add a dummy STA entry before completing TDLS
Setup and then update information on this STA entry based on what was
received from the peer during the setup exchange.

In theory, this could use NL80211_ATTR_STA_AID to set the peer AID just
like this is used in AP mode to set the AID of an association station.
However, existing cfg80211 validation rules prevent this attribute from
being used with set_station operation. To avoid interoperability issues
between different kernel and user space version combinations, introduce
a new nl80211 attribute for the purpose of setting TDLS peer AID. This
attribute can be used in both the new_station and set_station
operations. It is not supposed to be allowed to change the AID value
during the lifetime of the STA entry, but that validation is left for
drivers to do in the change_station callback.
