Make CarUserService dependent on CarUserManagerHelper (temporarily)

- While CarUserManagerHelper is being deprecated, CarUserService
continues to depend on CarUserManagerHelper.
- The changes made for the deprecation should be applied consistently,
and it is easier to track the changes in one place.
- At the end of the deprecation process, we will decide where to put
CarUserManagerHelper's APIs that are required by CarUserService.
- Two methods in CarUserManagerHelper are changed to public.

Bug: 141887102
Test: Run CarUserServiceTest.
