Fix in-process QAxServers inside modal windows.
The main window of in-process QAxServers doesn't have QWindow parent,
but it does have native parent that is part of the native window tree
of the application. The lack of Qt parent makes embedded controls look
like toplevel windows, which causes problems e.g. with modality.
Introduced new optional method QPlatformWindow::isEmbedded() to
detect if a window is an embedded window and utilized it in proper
places during modality handling.
Task-number: QTBUG-26871
