…ters The code was doing the same as the helper added in pythonGH-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. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

_sqlite3, update the comment that it is used in AC generated code as well.cc: @eendebakpt , @methane . Found this while working on moving
strto Argument Clinic generated code. The call + local rather than pointer to stack member, particularly when-fstack-protector-strongis set as some distros do, gets a lot shorter.
