[Provider Model] Refactor AirplaneSafeNetworksSliceTest
- The AirplaneSafeNetworksSliceTest should restore Airplane Mode state
after tear down
- Create AirplaneModeRule to backup/restore Airplane Mode state
automaticlly
- Plan to reuse the AirplaneModeRule for other test case
Bug: 173413889
Test: atest -c AirplaneSafeNetworksSliceTest
