Always give Qt::SubWindows a default window state of Qt::WindowNoState

Browse Source 
On platforms such as iOS, the default window state is Qt::WindowMaximized,
so that calling show() will fill the entire screen. But sub-windows should
not get this treatment, as their geometry is typically managed manually.

Pick-to: 6.2 6.2.0
