gh-50644: Forbid pickling of codecs streams (GH-109180)

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.
