eglfs: Call destroy() from dtors of concrete windows
Calling destroy from the QEglFSWindow dtor() triggers the virtual
invalidateSurface() to be called on a partly destroyed object. As the
child windows deregister themselves from their screens on
invalidateSurface() this is dangerous: It leaves a dangling pointer in
the screen.
Fixes: QTBUG-75075
