Set Qt::SubWindow on windows embedded by QWidget::createWindowContainer

Browse Source 
The embedded window is parented into the containing QWindowContainer
widget, which may either have a window handle itself, or is a child
of a widget that has one (typically the top level).

By setting Qt::SubWindow we inform clients about the embedded window's
place in the world, allowing e.g. QPlatformIntegration::defaultWindowState
to choose the correct state (Qt::WindowNoState) for the window instead of
making it Qt::WindowMaximized on iOS.

Pick-to: 6.2 6.2.0
