bpo-40696: Fix a hang that can arise after gen.throw() (GH-20287) This updates _PyErr_ChainStackItem() to use _PyErr_SetObject() instead of _PyErr_ChainExceptions(). This prevents a hang in certain circumstances because _PyErr_SetObject() performs checks to prevent cycles in the exception context chain while _PyErr_ChainExceptions() doesn't. (cherry picked from commit 7c30d12bd5359b0f66c4fbc98aa055398bcc8a7e) Co-authored-by: Chris Jerdonek <chris.jerdonek@gmail.com>
