This API does nothing..., and I think the 'Please remove ...' can be omitted

I added @serhiy-storchaka to reviewer because he is author of USE_UNICODE_WCHAR_CACHE. |

Nothing wrong stood out after a quick scan on my phone. The change seems mostly mechanical and limited to removals. Is that right?
Also, should the PEP be mentioned more prominently in the Misc/NEWS entry and whats_new?

What if merge #12409 first and set HAVE_UNICODE_WCHAR_CACHE to 0? It will have an effect of removing wstr, but keep possibility to return it in custom builds. |

I think it is very difficult to maintain both of HAVE_UNICODE_WCHAR_CACHE is 0 and 1.
AC supports u and Z even after removing wstr. I will replace Py_UNICODE with wchar_t in the clinic howto. |
Implemented in python/cpython#92537

Congratulations for finally managing to remove this legacy API. A big thank you! I hated this API since Python 3.3, having to call "PyUnicode_Ready()" was super annoying. Thanks for you tenacity to remove it! |
