Fabric: ScrollView: xplat part (shadow node, props, localdata, descriptor)

Summary:
All the props of a scrollview, and local data.
LocalData part is probably the most interesting: with it we precompute content size which we use inside native scrollview. Previously we rely on some assumptions like "ScrollView must have only one subview" instead, and that was not so efficient and straight-forward.
