bpo-45574: fix warning about `print_escape` being unused (GH-29172)



It used to be like this:

Quick `grep` tells that it is just used in one place under `Py_DEBUG`: https://github.com/python/cpython/blame/f6e8b80d20159596cf641305bad3a833bedd2f4f/Parser/tokenizer.c#L1047-L1051

I am not sure, but it also looks like a private thing, it should not affect other users.
