Destroy navigation activity layouts on catalyst instance destroy

addresses #2331 & Microsoft/react-native-code-push#1144

Use Case: When exposing the layout, other android code can check what kind of layout it is and react accordingly, fx:
```
if (activity.getLayout() instanceof BottomTabsLayout) {
    // ...
}
```

when compileSdkVersion is 25, below error was occured in react native 0.56.0.
"No resource found that matches the given name: attr 'android:keyboardNavigationCluster'"
so i have to change compileSdkVersion to 26.
Please add this push on your repository.
Thanks

Added a header to the sidebar to indicate that this is the V1.1.X documentation and added a link to the V2 docs.

Changed "assums" to "assumes".

Due to a race condition, the height and width of the Lightbox screen
may be read too early, resulting in a zero-width or height lightbox.

By default RTL is not enabled on the MaterialMenuDrawable of which the LeftButton extends. This results in the back button not being flipped when running your app against a right-to-left language. Enabling RTL for the LeftButton fixes this behavior and correctly flips the button when needed.

- We do that in order to allow the end user to decide
wether they want to destroy the host based on who's
the one calling onDestroy.
