Summary:
This diff attempts to fix a number of iOS native animation bugs related to improper node invalidation and a race with view creation. The major issues were presented in #9120 as problems 3 and 3b, but I'll recap here:
The invalidation model we use is overly complicated and incomplete. The proper combination of `_needsUpdate` and `_hasUpdated` will result in nodes values being recomputed. However, we do not invalidate nodes in all the places we should, e.g. if we create a new view and attach it to an existing value node (see example in #9120). This diff chooses to remove the `_hasUpdated` flag, and simply relies on the `_needsUpdate` flag to mark a node as dirty.
We mark nodes as dirty when they are:
- created
- updated
- attached to new parents
- detached from old parents
- attached to a view
Calling `updateNodeIfNecessary` will, if necessary, compute all invalidated parent values before recomputing the node value. It will then apply the update, and mark the no

Summary:
This diff addresses the issues raised by kmagiera in https://github.com/facebook/react-native/pull/7884. Transforms should be applied in the order they are defined, just like in `processTransform.js`. A scale applied before a translation, for instance, should give a different result than a translation applied before a scale.
We leverage CATransform3D to do the heavy lifting. A concatenated transform is passed all the way to `RCTViewPropertyMapper`. It is compared with the transform currently applied to the view, and if different, applied. The same approach is used for opacity.
I think it makes the most sense to do this diffing in `RCTViewPropertyMapper`, as opposed to creating and cleaning up an `_updatedPropsDictionary` each frame in `RCTTransformAnimatedNode` and `RCTStyleAnimatedNode`. The node should keep its full value; applying a minimal set of altered props is an optimization. The higher up this optimization is implemented, the more assumptions it makes. e.g. that there will only ever be a sing

Summary:
Currently on iOS animations are being performed on the JS thread. This ports animations over to the native thread and performs them natively. A lot of this work has already been done on Android, but this PR enables a few animation nodes that Android doesn't yet support such as Transform, Multiplication, and Addition nodes.
Also there is a demo of the native animations added to the UIExplorer app.
