gh-106320: Remove _PyUnicode_TransformDecimalAndSpaceToASCII()

[vstinner]

Remove private _PyUnicode_TransformDecimalAndSpaceToASCII() and other private _PyUnicode C API functions: move them to the internal C API (pycore_unicodeobject.h). No longer most of these functions.

Replace _testcapi.unicode_transformdecimalandspacetoascii() with _testinternal._PyUnicode_TransformDecimalAndSpaceToASCII().

• Issue: C API: Remove private C API functions (move them to the internal C API) #106320
