Subject: [PATCH] Fix enum_type_object type on Python 3.11
The enum_type_object type inherits from PyLong_Type which is not tracked
by the GC. Instances doesn't have to be tracked by the GC: remove the
Py_TPFLAGS_HAVE_GC flag.
The Python C API documentation says:
"To create a container type, the tp_flags field of the type object
must include the Py_TPFLAGS_HAVE_GC and provide an implementation of
the tp_traverse handler."
https://docs.python.org/dev/c-api/gcsupport.html
The new exception was introduced in Python 3.11 by:
