Summary: This is reimagining of interoperability layer between Yoga and ShadowViews (at least in Yoga -> RN part). Goals: * Make it clear and easy. * Make clear separation between "what layout what", now parent always layout children, noone layout itself. * Make possible to interleave Yoga layout with custom imperative layout (may be used in SafeAreaView, Text, Modal, InputAccessoryView and so on).
