camera2-portability: Remove Camera.CameraInfo accessor

This removes the CameraDevice#getCameraInfos() call that provided direct access
to this API 1 type, replacing it with another accessor returning individual
instances of the new wrapper type CameraDevice.BasicCharacteristics .
It also gives CameraProxy a method for getting instances of this wrapper.
