✨ Cirrus CI (#192)

With this PR, Apple Silicon wheels are natively built on Cirrus CI and
testing is enabled. In addition, Linux ARM wheels are built there.
Furthermore, Qiskit now ships Python 3.11 wheels; so testing wheels
under that Python is no longer skipped.

🔥 This PR drops `musllinux` wheels since `qiskit` also doesn't provide
corresponding wheels. As a result, Qiskit has to be built from source
under these systems anyway.

Overall, this considerably simplifies the Python wheel setup.

Solves #149
