Summary:
We need it to stop repeating to commit new shadow tree in `ShadowTree::commit` when a transaction cancels the commit.

Summary:
Fabric Core does not support exception safety, so technically exceptions are unrecoverable and binaries should be built without exception support.
While it's not the case, some exceptions might bubble to JavaScript realm and be caught as JavaScript exceptions. In this case, we lose the stack trace. To prevent that and to investigate one particular error we have we add this try-catch block in this diff.

Original commit changeset: 5cb78a3a75a7
In D23151218 (https://github.com/facebook/react-native/commit/dffec8bc7bee4d05b72d19b4efe4aeab980f4cd5) we switched from `ShadowTree::tryCommit` to `ShadowTree::commit` inside `UIManager::updateState`.
It fixes update state being dropped but can cause an infinite loop inside `ShadowTree::commit` because the shadow node that triggered `UIManager::updateState` can been removed before the `updateState` call is dispatched..

Summary:
Changelog: [internal]
In D22940187 (https://github.com/facebook/react-native/commit/774dec1e17f6f250172a6d4d944121b82fa36efb) we introduced a mechanism to retry failed state updates from view layer.
The mechanism fixes an issue where state update is occasionally dropped with background executor enabled.
# Why is state dropped?
The state is dropped because with background executor enabled, it is possible to enter `ShadowTree::tryCommit` for the same tree from 2 different threads at once. One of thread changes `_rootShadowNode` causing the other commit to fail.
The code goes like this:
```
{
Lock mutex
grab reference to `rootShadowNode_` and call it `oldRootShadowNode`
Unlock mutex
}
State reconciliation
Trigger layout
`rootShadowNode_` is untouched in this section.
{
Lock mutex
Check if `oldRootShadowNode` is equal to `rootShadowNode_`, if not, return false signalling failure. Now this is what happens when
state update fails.
..... not relevant
Unlock mutex
}
..... not relevant
```
However, in D22940187 (https://github.com/facebook/react-native/commit/774dec1e17f6f250172a6d4d944121b82fa36efb), we have taken another path. Instead of retrying to commit transaction, client is informed about the failure and it is left up to them to retry. This is correct and works. But I think it is unnecessary to this retry can be done inside UIManager::updateState.
In this diff I call `ShadowTree::commit` (version with retries) in case no `stateUpdate.failureCallback` is provided.
This makes sure that we do retry if state update fails but if Android implements `stateUpdate.failureCallback`, it is left up to view layer to retry.
Eventually we might decide to converge these two approaches.

Summary:
There are a few places where we cast JSI values to objects without much validation and without proper error logging, and in some places the crashes aren't symbolicated well. To make debugging easier in the short-term, I'm adding some additional logs.

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:
Hook up onSuccess and onFailure callbacks to LayoutAnimations.
Note that in non-Fabric RN, onSuccess is not known to work in Android. I could not find any uses of onFailure and it's not documented, so for now, it is only called if the setup of the animation fails.
