Valentin SherginandFacebook Github Bot 28e89e5081 Fabric: ShadowNodeFamily, the first steps
Summary:
ShadowNodeFamily is a new concept that allows us to implement an efficient way to solve the problem of finding a path to some ancestor node (practically reimplement ShadowNode::constructAncestorPath() in some efficient way).

This diff is the first one in the series. It introduces a new class and moves some data into it.
