* gh-157407: Use _PyUnicode_AsUTF8NoNUL for AC 's' and 'z' converters The code was doing the same as the helper added in GH-111957 but inline. That resulted in significantly more `.text` for most functions. Refactor the Arguemnt Clinic converters code to deduplicate a bit while keeping generated code close to original. On my Linux x64 box this reduces `.text` by ~6200 bytes in a clang release build (no PGO or LTO). Performance is flat. The helper was already exported for `_sqlite3`, update the comment that it is used in AC generated code as well.

This directory contains a number of Python programs that are useful
while building or extending Python.
build Automatically generated directory by the build system
contain build artifacts and intermediate files.
buildbot Batchfiles for running on Windows buildbot workers.
c-analyzer Tools to check no new global variables have been added.
cases_generator Tooling to generate interpreters.
clinic A preprocessor for CPython C files in order to automate
the boilerplate involved with writing argument parsing
code for "builtins".
freeze Create a stand-alone executable from a Python program.
ftscalingbench Benchmarks for free-threading and finding bottlenecks.
gdb Python code to be run inside gdb, to make it easier to
debug Python itself (by David Malcolm).
i18n Tools for internationalization. pygettext.py
parses Python source code and generates .pot files,
and msgfmt.py generates a binary message catalog
from a catalog in text format.
importbench A set of micro-benchmarks for various import scenarios.
inspection Tooling for PEP-678 "Safe external debugger interface for CPython".
jit Tooling for building the JIT.
lockbench Benchmarks for PyMutex and critical sections.
patchcheck Tools for checking and applying patches to the Python source code
and verifying the integrity of patch files.
peg_generator PEG-based parser generator (pegen) used for new parser.
pixi-packages Pixi package definitions for downstream from-source builds.
scripts A number of useful single-file programs, e.g. run_tests.py
which runs the Python test suite.
ssl Scripts to generate ssl_data.h from OpenSSL sources, and run
tests against multiple installations of OpenSSL and LibreSSL.
tsan Utilities for building CPython with thread-sanitizer.
unicode Tools for generating unicodedata and codecs from unicode.org
and other mapping files (by Fredrik Lundh, Marc-Andre Lemburg
and Martin von Loewis).
unittestgui A Tkinter based GUI test runner for unittest, with test
discovery.
wasm Config and helpers to facilitate cross compilation of CPython
to WebAssembly (WASM).
