Add @nullable to ScrollView getChildVisibleRect offset parameter

Summary:
The `offset` parameter in `getChildVisibleRect` overrides was missing the
`Nullable` annotation. The Android framework contract for
`ViewGroup.getChildVisibleRect(View, Rect, Point)` allows `offset` to be null,
and `View.getGlobalVisibleRect(Rect)` legitimately passes null. The `Nullsafe`
instrumentation injected a non-null assertion that crashed when null was passed.

Changelog:
[Android][Fixed] - Fix NullPointerException in ScrollView `getChildVisibleRect` when `offset` is null
