Remove SCREEN from lightbox layout (#6124)

* Assign an ID to lightbox and use it as a key

* Consolidate lightbox props into an object

* Remove unused prop

* Move SafeAreaView declaration

* Keep SafeAreaView always mounted

When exploring Android animation, I noticed its content jumps on the first frame. I think this should help prevent that.

* Pass safe area down for measurement

* Remove dependency on SCREEN in Android event handlers

* Remove dependency on SCREEN in iOS event handlers

* Remove dependency on SCREEN on iOS

* Remove dependency on SCREEN on Android

* Remove dependency on JS calc in controls

* Use flex for iOS layout
