Android: Make QtWindow wrap the QtLayout instead of inherit it

The layout is a ViewGroup, and should be created in the Android UI
thread, while for ease of use on C++ side we should be able to
construct the Java object in the platform window constructor to
avoid later calls not having a valid object reference. Trying to
make a blocking call to Android thread from Qt thread can lead to
dead locks, so move only the creation of the layout itself into
Android thread, making the QtWindow a wrapper for it, which we can
immediately return to C++/Qt thread. Most of the calls made to
QtWindow are anyway already passed to the Android UI thread.

As a drive by, add a missing QtNative.runAction() to
bringChildToFront().
