Tools/scripts/ to Tools/build/:

* check_extension_modules.py
* deepfreeze.py
* freeze_modules.py
* generate_global_objects.py
* generate_levenshtein_examples.py
* generate_opcode_h.py
* generate_re_casefix.py
* generate_sre_constants.py
* generate_stdlib_module_names.py
* generate_token.py
* parse_html5_entities.py
* smelly.py
* stable_abi.py
* umarshal.py
* update_file.py
* verify_ensurepip_wheels.py
