Add NativeLogBox module on Android

Summary:
This diff adds a NativeLogBox module implementation on Android to manage rendering LogBox the way we render RedBox, except rendering a React Native component instead of a native view.

The strategy here is:
- initialize: will create a React rootview and render it.
- show: will add the rootview to a dialog and display the dialog.
- hide: will remove the rootview from it's parent, dismiss the dialog, and release the reference to the activity to prevent leaks.

Most of this is copied from the way RedBox works, the difference here is that we eagerly initialize the rootview with the `initialize` function so that it's warm by the time the dialog needs to render.
