bpo-36829: PyErr_WriteUnraisable() normalizes exception (GH-13507)

Browse source 
PyErr_WriteUnraisable() now creates a traceback object if there is no
current traceback. Moreover, call PyErr_NormalizeException() and
PyException_SetTraceback() to normalize the exception value. Ignore
silently any error.
