RN: Update ViewConfig for ScrollView

Summary:
Updates `ReactScrollViewManager` and the `ViewConfig` for `ScrollView` so that they are equivalent.

- `inverted` was missing.
- `contentOffset` was missing differ on Android. (However, there does not seem to be any perceivable behavior difference besides the native `ViewConfig` being different.)
