bpo-41789: honor object overrides in Enum classes (GH-22250)

Browse source 
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.
