Support text decoration in QML when using static text back-end

When the QStaticTextItem code path in QML was copy-pasted, QStaticText
did not support text decoration yet. It has since been implemented.
We copy-paste the fix as well (which means we have to export a
private function from QtGui to avoid duplicating that code as well.)
