Add useNativeDriver to shine animations

[ovistoica]

Make Shine and ShineOverlay animations run on the native thread. Related to this issue: https://github.com/mfrachet/rn-placeholder/issues/99

Only remaining animation on the JS side is Progressive. I think this is still possible but I would want to start a discussion regarding this. For using translateX as the animated prop you need the width of how much to translate.

My attempts at converting Progressive were making the animation look different from the initial one because the Progressive View was the same width on all children (Left, Right or Other Media) therefore translating with 50% would look different on lines of different length and it was not possible to find the width of the PlaceHolderLine or Media to translate only by that, as the Animation Consumer was put inside the View and not on the outside.

Example

In the picture above, I translated the AnimatedView with -20%, as you can see, in the Left and Right media, this shows a progress of 50% because the View is translated by 20% of its own width.

A possible solution would be to define the AnimationConsumer inside the PlaceholderLine and PlaceholderMedia so that you can pass through that context an onLayout function that can get the width of the parent.

I considered that to be a bit too much of a reimplementation, but that would solve the problem. If you give the alright for that, I would provide a different PR with this.

Until then, here is Shine and ShineOverlay 😄
