nl80211: Beacon protection capability flag and default key type

Browse source 
Add a new capability flag based on the nl80211 feature advertisement and
start using the new default key type for Beacon protection. This enables
AP mode functionality to allow Beacon protection to be enabled. This is
also enabling the previously added ap_pmf_beacon_protection_* hwsim test
cases.
