Move resizeOverlay() to QQuickPopupPrivate

This is a preparation step for making drawers movable. Drawer must
be later able to resize the overlay to fit the area of the window
that is covered by the drawer. For example, if the Drawer is below
the header, it can resize the overlay so that it won't be on top of
the header.
