feat: Add s390x release (#1352)

Include s390x in release and update python-build-standalone to 3.9.17,
3.10.12, 3.11.4.
[Latest python-build-standalone
release](https://github.com/indygreg/python-build-standalone/releases/tag/20230726)
has s390x support added.

These changes are needed to build TensorFlow on s390x, which is
currently blocked due to missing support.
