QGraphicsAnchorLayout: port to QHVContainer [3/4]: Orientation as alias for Qt::Orientation

There would still be too many renames, so keep the
locally-defined names 'Orientation', 'Horizontal', and
'Vertical' as deprecated forwarders to Qt::Orientation,
Qt::Horizontal and Qt::Vertical, resp.

Follow-up patches will remove these, then, completely.
