Moved CameraRoll-related classes into CameraRoll folder instead of Image
Summary: The CameraRoll-related APIs were mixed in with the Image classes due to legacy coupling issues. Now that the APIs have been decoupled, it makes more sense for the CameraRoll classes to live in a separate library. This will be a breaking change for apps using the CameraRoll or related APIs. Fix is to add the RCTCameraRoll lib to your project.
