bpo-41789: honor object overrides in Enum classes (GH-22250) 
EnumMeta double-checks that `__repr__`, `__str__`, `__format__`, and `__reduce_ex__` are not the same as `object`'s, and replaces them if they are -- even if that replacement was intentionally done in the Enum being constructed.  This patch fixes that.

Remove binding of captured exceptions when not used to reduce the chances of creating cycles (GH-17246) 
Capturing exceptions into names can lead to reference cycles though the __traceback__ attribute of the exceptions in some obscure cases that have been reported previously and fixed individually. As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles.

See for example GH-13135

Gregory P. Smith ext:(%20%5BGoogle%20Inc.%5D) 6f20bd6063 signal, socket, and ssl module IntEnum constant name lookups now return a 
consistent name for values having multiple names.  Ex: signal.Signals(6)
now refers to itself as signal.SIGALRM rather than flipping between that
and signal.SIGIOT based on the interpreter's hash randomization seed.

Ethan Furman e03ea37a7b Close #19030: improvements to inspect and Enum. 
inspect.getmembers and inspect.classify_class_attrs now search the metaclass
mro for types.DynamicClassAttributes (what use to be called
enum._RouteClassAttributeToGetattr); in part this means that these two
functions no longer rely solely on dir().

Besides now returning more accurate information, these improvements also
allow a more helpful help() on Enum classes.
