gh-105156: Update Unicode C API: remove deprecation (#105379)

vstinner · web-flow · commit 04181965cfd3 · 2023-06-06T16:42:49.000+02:00
_PyUnicode_ToLowercase(), _PyUnicode_ToUppercase(),
_PyUnicode_ToTitlecase() are no longer deprecated in the
documentation. It's no longer needed since they now use Py_UCS4 type,
rather than the deprecated Py_UNICODE type.
