feat(typings): Adding Android typings for API levels from 17 to 27 (#5890)

Adding android typings for API levels from 17 to 27

BREAKING CHANGES:
There is no longer added `I` prefix in the names of the interfaces. For example `android.view.IMenuItem` is now `android.view.MenuItem`. This matches the original name of the interface in the android framework.
