Samuel Susla 283512cc42 Fix Yoga's right to left offset in horizontal scroll view
Summary:
Changelog: [internal]

Yoga offsets content view of scrollview in RTL environment. React Native Classis deals with it by using a separate component [ScrollContentView](https://github.com/facebook/react-native/blob/6e6443afd04a847ef23fb6254a84e48c70b45896/React/Views/ScrollView/RCTScrollContentShadowView.m#L18-L25
) and making the adjustment there.

In New React Native Renderer, it can be handled inside `ScrollViewShadowNode`.
