[3.11] gh-50644: Forbid pickling of codecs streams (GH-109180) (GH-109232)

Attempts to pickle or create a shallow or deep copy of codecs streams
now raise a TypeError.

Previously, copying failed with a RecursionError, while pickling
produced wrong results that eventually caused unpickling to fail with
a RecursionError.
(cherry picked from commit d6892c2b9263b39ea1c7905667942914b6a24b2c)
