The new version of ICameraDeviceCallback supports shutter notify with readout timestamp. The readout timestamp is used to re-time viewfinder frames to reduce jitter. When camera runs at fixed frame rate, the start_of_exposure time intervals may change, but start_or_readout intervals are constant. Test: Camera VTS test Bug: 189380857 Change-Id: I4c3856a4e30caa8cdf8417d437de1de3190c6fd6
