Summary:
Fixes#10638.
Added NativeAnimation library to the starter project iOS generator. Passing `useNativeDriver: true` to `Animated` config will enable the app to tap into the native code for animations.
**Test plan**
Init a RN project and animate an element. Enable native driver as follows:
```
Animated.timing(
this.state.value,
{
toValue: 300, // some value
useNativeDriver: true
}
).start();
```
Earlier, this used to crash.
