Update permissions for Licenses and Licenses Controllers

What does this MR do?

A part of #13247 (closed)

1. We remove licenses_list license feature to simplify permissions. License compliance page feature is based on License Management aka License Compliance analizer so we just check if this second feature is available. Also, we add a condition for licenses_list feature flag, since this feature isn't publicly available yet. That will help to simplify rules and make fewer mistakes with permissions.
