Split QPlatformWindow::isEmbedded into isAncestorOf to separate concerns

The function was doing two things, both checking window ancestry and
whether or the window was a direct child of non-Qt window. The former
has now been split of in a QPlatformWindow::isAncestorOf(), which
simplifies the code in e.g. QApplicationPrivate::isWindowBlocked().
