wifi: mac80211: Advertise IEEE 802.1X authentication support

Advertise support for IEEE 802.1X authentication protocol directly from
mac80211, without depending on driver indication of (Re)Association
frame encryption capability.

As specified in "IEEE P802.11bi/D4.0, clauses 12.16.5 and 12.16.8.2",
IEEE 802.1X authentication can operate with or without (Re)Association
frame encryption support. Therefore, mac80211 can safely advertise
802.1X support independently of driver capabilities.
