Migrate from pyenv to uv

[edg-l]

This migrates the python workflow from pyenv to the fast modern rust based uv.

The only takeaway is that the pypy versions you can install from uv doesn't seem to work well with the bitarray dependency we have, as it fails to compile. As pypy was only used in run_benchmarks.sh, which was an outdated script that we no longer used, I also removed it.

I also tried to update python to 3.13.2 but cairo-run doesnt work well, however cairo-compile does work well. In the end I kept the old python version 3.9.

The non-required ci workflow Benchmark Hyper Threading / benchmark (pull_request) fails because main doesnt use uv yet

@edg-l I would consider to keep pyenv for now as an alternative if uv is not installed (I'm following #1754 as a reference). We can print a message with something like pyenv is deprecated if that's the case.
