Summary: This diff adds support for value offsets on iOS. It separates out code originally submitted in #9048. Test plan (required) Set up an animation with an offset, and `useNativeModule: true`. Compare results with `useNativeModule: false`. Closes https://github.com/facebook/react-native/pull/9627 Differential Revision: D3924410 fbshipit-source-id: 8177a25a5f6b9e33f00ea66143c782aeea24507d
