youknowdot 6e82636bee Add Python 3.15 encoding normalization helper (#9115 )

Extract _codecs._normalize_encoding and delegate encodings.normalize_encoding
to it using the final CPython 3.15 library source. Preserve case and dots,
validate UTF-8 before NUL truncation, and retain wrapper warnings and bytes
conversion. Add bounded regression assertions without changing registry keys.

Lib/encodings/__init__.py was updated via scripts/update_lib migrate from
CPython d220409a13b77de7a6c30abe16ea90db01528edc, with byte-identical output.

AI assistance: OpenAI Codex implemented and source-reviewed this split,
ran update_lib, prepared bounded regressions and performed focused automated
validation. No human manual testing is claimed.

README.md

Standard Library for RustPython

This directory contains all of the Python files that make up the standard library for RustPython.

Most of these files are copied over from the CPython repository (the 3.7 branch), with slight modifications to allow them to work under RustPython. The current goal is to complete the standard library with as few modifications as possible. Current modifications are just temporary workarounds for bugs/missing feature within the RustPython implementation.

The first big module we are targeting is unittest, so we can leverage the CPython test suite.
