Drop support for 32-bit platforms?

32-bit platforms seem pretty much obsolete (outside of embedded, which we don't actively support). There is no 32-bit version of Windows 11, and Windows 10 will reach EOL soon. All new desktop processors have been 64-bit for well over a decade now.

Does anybody have evidence that a non-trivial number of users are still using 32-bit platforms?

If we decide to move forward with this, we can start with not running CI on 32-bit platforms and updating documentation to not say that 32-bit platforms are supported (not sure if we ever make this explicit).

We can still keep the existing level of support in mypyc, in case somebody wants to maintain it in the future. If at some point there hasn't been any interest in fixing issues on 32-bit platforms for 6 months, we can think about removing all existing support.

Examinez la configuration CI existante et la documentation à la recherche de références à la prise en charge des plateformes 32 bits, et examinez séparément la prise en charge de mypyc. Rassemblez des éléments sur les utilisateurs actuels du 32 bits avant de décider si CI et la documentation doivent être modifiés ; le travail est considéré comme terminé lorsque la décision concernant la prise en charge et le périmètre qui en découle sont clairement consignés.
