Don't rely on QRasterWindow::resizeEvent for marking window dirty

The de-virtualization gotcha might result in client code not calling
QRasterWindow::resizeEvent, which we use for dirty state management
after e0eb2818face4ffb7dafd87464f355d4654b7be0.

In practice this wasn't an issue, because QPaintDeviceWindow handles
paint events by calling markWindowAsDirty first, but we should not
rely on this.

Instead plumb the resize event to QPaintDeviceWindowPrivate, which
QRasterWindow implements and can override the behavior of.
