QFuture: mention the work-stealing algorithm in the docs
A number of users have explored the behavior and complained about it.
Lets add a \note explaining this. The function in charge is
QThreadPool::stealAndRunRunnable(QRunnable *), which is a private
function, exclusively used by:
QFutureInterfaceBase::waitForResult()
QFutureInterfaceBase::waitForFinished()
also update the documentation to reflect these changes accordingly.
Fixes: QTBUG-112351
