This commit applies the various fixes needed to the wheel publishing job
definitions for the 0.13.0 release. There were several jon errors during
the release which were caused by various changes made to rustworkx,
upstream dependencies, and CI environment since the 0.12.0 which caused
issues during the release process. Qiskit#753 should still be finished to
simplify the job definitions, but that should be rebased to take this
more targeted fix. The intent is for this to be a minimal diff for
backporting to stable/0.13 for a future 0.13.1 release.

Of particular importance here though is the change in support tier for
s390x from 3 to 4. This was caused by repeated issues with timeouts
caused by running tests during the s390x linux wheel builds. To ensure
we can reliably build the wheels this drops the testing from the s390x
so that they can reliably complete in 12 job hours.
