Fix high DPI position of foreign child windows on Windows

Suppose you have a child window that is a foreign window.  In the bug
report's example it's a QAxWidget that wraps the Windows Media Player.

This means, we have a non-top-level QWindow with a platformWindow
assigned.  If windows:dpiawareness is set to 1 (system-DPI aware) and
the window is displayed on a screen with origin != (0, 0), then we
called QPlatformWindow::setGeometry with a position in native
coordinates.  This moved the child window outside of the visible area.

Fix this by calling QHighDpi::toNativeWindowGeometry instead of
QHighDpi::toNativePixels.  The former function takes child windows
properly into account.
