Android: Return QAndroidApplication instance via nativeInterface() getter

Browse Source 
The QAndroidApplication native interface wrongly uses static methods
instead of virtual functions, which has lead to client call sites not
using the preferred QCoreApplication::nativeInterface() API to resolve
the interface, and a lack of an implementation in QCoreApplication
for the resolveInterface function.

We now implement resolveInterface for Android, so that the interface
can be resolved via QCoreApplication::nativeInterface(), even if the
interface itself (for now) is based on static methods.

Task-number: QTBUG-128796
