Add NodeRegion to allow any FlatShadowNode to respond to touch events

Browse Source 
Summary: @public When Android dispatches `MotionEvent` to `ReactRootView`, it needs to find a correspoding react node that should receive it. To be able to do it, we need to store boundaries of every `FlatShadowNode` in `FlatViewGroup`. Then we can iterate over node boundaries and find one that contains the touch event coordinates.
