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
