QGuiApplication: use the rvalue overload of QObject::setProperty()

Said overload was added in 39cdf431f034121353e51768b4d1fec8b0dd35dc,
and its use prevents a forced detach in setProperty() that comes from
the function taking a copy of the QVariant and then calling .data()
on it. The rvalue overload prevents this.

Pick-to: 6.10 6.9 6.8
