Janic Duplessis df05311777 Add transform support for native animated on Android
Summary:
This adds support for the `transform` animated node. This brings feature parity with the iOS implementation and allows running the NativeAnimated UIExplorer example that was created with the iOS implementation on Android. This is based on some work by kmagiera in the exponent RN fork.

This also adds support for mixing static values with animated ones in the same transform as well which is not supported on iOS at the moment. It is also implemented in a way that rebuilds the transform matrix the same way as we build it in JS so it will be easy to remove some of the current limitations like forcing the transforms order and only supporting one of each type.

**Test plan (required)**

Tested with the NativeAnimated example on Android and iOS. Also tested mixing in static values in a transform (`[{ rotate: '45deg' }, { translateX: animatedValue }]`).

Ryan Gomba eb96b7fabc Maintain transform order
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

Brandon Withrow 19e2388a76 Add support for native animations on iOS
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.
Closes https://github.com/facebook/react-native/pull/7884
