build: add aarch64 manylinux wheel builds

[no23reason]

Use QEMU to enable builds of native aarch64 manylinux wheels. Also upgrade cibuildwheel to the latest version.
Inspired by https://cibuildwheel.readthedocs.io/en/stable/faq/#emulation
The aarch64 builds take +/- 10 minutes per python version, so the total build time increases quite a lot :( to reduce it somehow, maybe it would be worth it to drop support for end-of-life python versions 3.6 and 3.7?

Here is a sample run with a slightly different version (I was able to simplify it for the PR, but the semantics are the same): https://github.com/no23reason/sqlean.py/actions/runs/6586202390

@nalgeon could you please review this?

[nalgeon]

Not sure about this. Why do you folks need an ARM Linux build at all? Do you actually use Linux on ARM processors?

[no23reason]

Yes, unfortunately I do :( the use case is running an image that uses the sqlean dependnecy inside Docker and Docker compose on an Apple Silicon host.

[no23reason]

But I understand your concerns, the builds do take for ever :/ we develop some python wheels internally at our company and the support for the ARM/Linux version of our wheels also made our builds take twice as long compared to the x86 ones.

Fair enough. Thank you!
