gh-93820: Fix copy() regression in enum.Flag (GH-93876) (#93886)
GH-26658 introduced a regression in copy / pickle protocol for combined
`enum.Flag`s. `copy.copy(re.A | re.I)` would fail with
`AttributeError: ASCII|IGNORECASE`.
`enum.Flag` now has a `__reduce_ex__()` method that reduces flags by
combined value, not by combined name.
(cherry picked from commit 05b32c1c796d6c80479756ae898f488eac5f4f71)
