tst_qstringapisymmetry: check QString/QAnyStringView overloads w/Q_WEAK_OVERLOAD flipped

This overload set may come in handy to cushion some of the concerns
regarding replacing QString functions with QAnyStringView ones.

Overloading with a Q_WEAK_OVERLOAD QAnyStringView function requires
users to jump through hoops in order to avoid the QString overload,
but with the Q_WEAK_OVERLOAD roles reversed, the QAnyStringView
overload becomes the preferred version, relegating the QString
overload to a fall-back to facilitate sharing where it makes sense
(e.g. for QObject::setObjectName()).
