Display 'License-Check' approval rule in the license compliance section
Context: this issue is based on discovery work done in https://gitlab.com/gitlab-org/gitlab-ee/issues/12941, where a policies section was added to license compliance.
License-Check can only be done in settings > general > MR approvals. Additionally, the feature is not visible in the UI.
Display in License Compliance > Policies
License-Check: 1) ability to edit/on/off the check, 2) notify the user when
license-check is activated (add tooltip as seen in the MR)
