wifi: iwlwifi: mvm: d3: parse keys from wowlan info notification

This notification replaces the WOWLAN_GET_STATUSES command-and-response,
so it's required to parse all the keys in the notification just like
what happened when that command was used.

Move around a few required static functions in order to avoid forward
declarations.
