cameraserver: Enforce system only camera permissions in camera1 api.
In camera1 api
- getNumberOfCameras won't count hidden secure cameras.
- getNumberOfCameras will return public non system cameras or public
cameras depending on whether the client has SYSTEM_CAMERA and CAMERA
permissions or not.
- getCameraInfo checks for SYSTEM_CAMERA and CAMERA permissions in case
the info is requested for a system camera.
