Camera: Improve metadata access JNI performance - Don't use reverse-JNI to access metadata ptr, pass it as an arg instead - Use @FastNative since the calls are short and bounded in time Performance improvement: - On a 10-second trace of camera app running on sargo, percentage of time used in CameraMetadataNative.get went from 4.36% to 3.77%, a 15% reduction in time. Test: atest CtsCameraTestCases Bug: 150214459 Change-Id: I28d9428beaa7eada6292e24fe6ca1dbd9c2ff153
