Summary:
Cards which are not visible because another card is occluding them are still being rendered by Android resulting in overdraw. This results in wasted GPU time because some pixels are drawn multiple times. This change reduces overdraw by changing the opacity of occluded cards to 0.
This bug was found using the tools described in Android's overdraw docs: https://developer.android.com/topic/performance/rendering/overdraw.html
**Test plan (required)**
This change is being used in my team's app.

Summary:
The `position` animated value is used for scale, translateX, and tranlateY
animations, which are all supported by NativeAnimatedHelper. Unfortunately,
native animations are incompatible with JS driven animations, which the
`enableGestures` flag enables.
This diff therefore conditionally enables native animations based on the native
module's precense, and the state of `enableGestures`.
Ideally the animations would be refactored so that they could fully leverage
native animations, as they are far superior for navigational components.

Summary:The initial layout used to render scenes does not contain the actual
width and height measured and causes the issue as described at
https://github.com/ericvicenti/navigation-rfc/issues/61
The fix is to update the layout and re-render scenes once layout
is modified. Also scenes renderer should also consider the case that
when the layout is not measured yet.

Summary:Per offline discussion with ericvicenti, we'd like to reudce the complexity by
keeping <NavigationCard /> nothing more than just a simple `<Animated.View />`,
which helps us to avoid over generalize the styles, gestures of what the Navigation card
needs to be.
The proposalis to use the same props (NavigationSceneRendererProps) that is used to render
the scene to generate the style and pan handlers needed for the navigation card.
No behavior changes, just implementation details clean up work.
