feat(mobile): multi-window support

[lucasfernog]

Leverages scenes on iOS and Activity embedding on Android.

All window APIs are now exposed on mobile too. Some of them are still ignored though (like setting a title).

iOS

• Added RunEvent::SceneRequested (on iPad the user can request a new window to be open - e.g. by long pressing the app icon and selecting "New window")

Android

• Added builder methods to determine the activity to be created. System determines what to do with the activity (new stack, next to another one.. based on the embedding rules)
