tests: RSN pre-auth and PMKSA caching with per_sta_vif
This adds new tests to verify pmksa_cache_preauth when used with per_sta_vif and possibly vlans. While at it it refactors the code such that the tests pmksa_cache_preauth pmksa_cache_preauth_vlan_enabled pmksa_cache_preauth_vlan_used pmksa_cache_preauth_per_sta_vif pmksa_cache_preauth_vlan_enabled_per_sta_vif pmksa_cache_preauth_vlan_used_per_sta_vif share code where possible.
