Valentin Shergin f91f7d91a1 Reimagining of RCTShadowView layout API
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).
