Summary:
This replaces the internal core implementation of `setState` with the new `updateStateWithAutorepeat` which is now the only option.
In short, `updateStateWithAutorepeat` works as `setState` with the following features:
* The state update might be performed several times until it succeeds.
* The callback is being called on every retry with actual previous data provided (can be different on every call).
* In case of a static value is provided (simple case, not lambda, the only case on Android for now), the same *new*/provided value will be used for all state updates. In this case, the state update cannot fail.
* If a callback is provided, the update operation can be canceled via returning `nullptr` from the callback.
This diff removes all mentions of the previous state update approach from the core; some other leftovers will be removed separatly.

Summary:
This is *another* attempt to solve a failed state update problem.
Unfortunately, some applications are inherently not compatible with the "let's recommit the update on the application side in case it failed" approach. The problem is that if we call `updateState` on the application side, we miss the original event window. E.g. if we need to deliver some state update with AsyncBatched priority and if the update fails, we lose the opportunity to commit it on time. These issues can be critical for some complex use-cases as ComponentKit interop.
This diff adds implementation for `updateState` that does the work a bit differently. For all failed state updates it tres to recommit them asap using `ShadowTree::commit` and calling lambda on every attempt. With this approach the update might fail in two cases:
The node disappeared from the tree, so there is no way to update it.
The lambda returned `nullptr` indicating that the update is no longer needed.
We need this for the ComponentKit interoperability layer that is very sensitive for missing state updates.

Summary:
iOS will need to be implemented separately, but the shared C++ bits are in place.
Explanation: there is currently no way for the View layer to /know/ if an UpdateState call has succeeded or failed. Generally we just assume it succeeds, but if it fails we have no way of knowing or retrying.
This can cause some UI bugs. To mitigate this, I'm introducing a "failure" notification callback mechanism. The JNI bridging for this is a little complicated to avoid passing Runnable across the JNI, but it
should be much simpler on iOS.
In development this seems to make View components much more reliable.

Summary:
This diff removes the inner folder of react/renderer/core, moving all its files into react/renderer/core
This is necessary to simplify the compilation of Fabric in OSS
