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:
`Animated.parallel` among other functions expects the `start(callback)` function to be invoked with an `endState` object. Currently natively driven animations call the handler with `null`, this PR changes that to `{ finished: true }`.
**Test plan**
This should not throw any errors:
```js
Animated.parallel([
Animated.timing(
new Animated.Value(0),
{
toValue: 1,
useNativeDriver: true
}
),
Animated.timing(
new Animated.Value(0),
{
toValue: 1,
useNativeDriver: true
}
)
]).start();
```

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.
