Store std::exception_ptr in QUnhandledException
For historical reasons Qt Concurrent reports QUnhandledException in
case if an exception that is not derived from QException is thrown
from a worker thread. Changing this behavior may not be a good idea,
since the existing user code may rely on it. Changed QUnhandledException
to wrap the std::exception_ptr to the actual exception, so that the
users can obtain the information about the thrown exception if needed.
[ChangeLog][QtCore][QUnhandledException] Improved QUnhandledException to
store the std::exception_ptr to the actual exception thrown from a
QtCocnurrent worker thread.
