Summary:`scrollResponderInputMeasureAndScrollToKeyboard` is the only non-deprecated method in `ScrollResponder.js` that doesn't use the [new `scrollTo` API](6941c4e027). The other method that uses the deprecated API (`scrollResponderScrollWithoutAnimationTo`) is also deprecated, so it has been left unaltered.
