Subject: [PATCH] Fix the Portal display to not rerender the entire tree

Summary:public
We now wrap the	<RootComponent>	in an <View> where we can control the accessibility at a high level.  This was only used to turn it off for the faded out background view when we show a pop up.

We use setNativeProps instead of setState to avoid the render.	  We really just want to pass this value to the native Android View.
