Joshua Gross bdea479a1f Fix Android crash: mark re-created nodes in Differ
Summary:
Android has some optimizations around view allocation and pre-allocation that, in the case of View Unflattening, can cause "Create" mutations to be skipped.

To make sure that doesn't happen, we add a flag to ShadowViewMutation (in the core) that any platform can consume, that indicates if the mutation is a "recreation" mutation.

It is still a bit unclear why this is needed, in the sense that I would expect props revision to increment if a view is unflattened. However, there is at least one documented reproduction where that is *not* the case. So for now, we'll have a hack pending further investigation.

Joshua Gross e8770d7bb2 Code quality: Refactor ShadowViewMutation::UpdateMutation to remove index, parentShadowView parameters
Summary:
The `index` parameter for UpdateMutation is optional, and is normally just -1. It's not useful, so remove it. `parentShadowView` is also not relevant and is not used; in some existing use-cases the actual parent view of the updated view is available, and in some contexts the parent view is not set.

The function now will always set the index to -1 for UpdateMutations, and `{}` for ParentShadowView.

This should have no impact on iOS or Android, as this parameter is not used. It could theoretically have an impact on lifetimes of objects retained (now not retained) by not passing parentShadowView into the mutation. For example, any shared props or state associated with the parent will not be retained in the Update mutation now.
