Update QQuickWidget::texture() override because of signature change

To support stereoscopic rendering in QOpenGLWidget using the RHI backend
QWidgetPrivate::texture return type was changed to accommodate the extra
texture required. This patch fixes the override for QQuickWidget to
return the new type, where the second texture is just a nullptr (not
used).
