wifi: cfg80211: add support for key configuration before association

Browse Source 
Currently, cfg80211 does not allow key installation, removal, or
modification prior to association in non-AP STA mode. However,
Enhanced Privacy Protection Key Exchange (EPPKE) requires encryption
keys to be managed before association.

Add support to manage keys before association in non-AP STA mode when
the NL80211_EXT_FEATURE_ASSOC_FRAME_ENCRYPTION feature flag is set.
If the flag is not set, reject the encryption keys.
