CameraService: Clean up ICameraServiceProxy; send it more info

- Remove hand-written ICameraServiceProxy C++ impl; use the AIDL-
  generated version instead
- Send client package name and camera facing with the camera state
  notices

Test: Verify by logging that information sent to proxy is correct;
      no camera CTS regressions.
