wifi: mac80211: allow key installation before association

Currently, mac80211 allows key installation only after association
completes. However, Enhanced Privacy Protection Key Exchange (EPPKE)
requires key installation before association to enable encryption and
decryption of (Re)Association Request and Response frames.

Add support to install keys prior to association when the peer is an
Enhanced Privacy Protection (EPP) peer that requires encryption and
decryption of (Re)Association Request and Response frames.

Introduce a new boolean parameter "epp_peer" in the "ieee80211_sta"
profile to indicate that the peer supports the Enhanced Privacy
Protection Key Exchange (EPPKE) protocol. For non-AP STA mode, it
is set when the authentication algorithm is WLAN_AUTH_EPPKE during
station profile initialization. For AP mode, it is set during
NL80211_CMD_NEW_STA and NL80211_CMD_ADD_LINK_STA.

When "epp_peer" parameter is set, mac80211 now accepts keys before
association and enables encryption of the (Re)Association
Request/Response frames.
