QTimer: fix API docs of callOnTimeOut overload

Browse Source 
It actually takes one parameter, because in this overload the connection
type can't be specified, for example:
QTimer timer;
timer.callOnTimeout([]() { qDebug() << "slot"; });

The call chain is:
QObject::connect(timer, &QTimer::timeout, functor);
connect(const typename QtPrivate::FunctionPointer<Func1>::Object *sender, Func1 signal, Func2 &&slot)
connect(sender, signal, sender, std::forward<Func2>(slot), Qt::DirectConnection);

the connection type is always DirectConnection.

Spotted by Giuseppe in code review.
