universal7904: Introduce libcamera_metadata_helper

* For supporting VNDK and Treble rules.

Issue: In accordance to treble rules libcamera_client.so cannot be
       used or included. For Camera HAL needed support for values of
       CameraMetadata

Solution: Included CameraMetadata.h and .cpp files to this helper lib for camera hal and replaced with libcamera_client.so.
