Revert "Remove obsolete Jamfile"

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:
