Valentin Shergin 33112a1c20 Fabric: Making State::getMostRecentState public
Summary: That was always part of design, that's okay to get a newer state from any other state. We will need it in the future diffs.

Valentin Shergin b491e8725a Fabric: ShadowNode::getCommitedState() does not crash now in case if there is no comited state
Summary: `Target` inside the Stage can be empty; in this case, we should not try to extract `ShadowNode` from it.

Valentin Shergin bd19f3bd13 Fabric: ShadowNode::getCommitedState() now returns by value
Summary: Returning a shared pointer by const reference in this context is not correct/safe because the object (the ShadowNode) doesn't own the object, so the caller cannot reason about the lifetime (esp. in a multithreaded environment).

Valentin Shergin 802534e611 Fabric: Introducting State, an escape path from unidirectional data flow
Summary:
In React Native there are several use cases where React State is not the only input that affects the component tree. E.g., in case of a <Modal> component, the screen size directly affects the layout of components inside modal; in the case of uncontrolled <TextInput> component, the text inside the input affects the layout of the surrounding components. `State` is a special (legit!) workaround for all those similar cases. Native part of React Native maintains a special shared object between all nodes of the same family and use that during cloning and commits.

See coming commits to know how to use that.

In the near future State will fully replace LocalData concept but for simplicity they both exist for now.
