`aarch64-apple-darwin/clang` JIT CI is broken

[brandtbucher]

This it seems that this started happening a bit after LLVM 19.1.3 was released. Failures look like this:

https://github.com/python/cpython/actions/runs/11686618553/job/32543252335#step:6:1233

For some reason, assert.h can't be found. So it appears that something about the LLVM install is broken.

For now, we'll start by skipping the jobs.

This actually happened to me while i tried to set up a local environment on my mac.
I tried several stuff but i think that running softwareupdate -i "Command Line Tools for Xcode-16.1" solved the issue.
will open a PR

I'll self-assign and take a look at this tonight, but also happy to review anyone's PR if someone figures it out before I do.

Hey @savannahostrowski - please take a look at #126494, seems to have fixed the issue (some jobs are still running, but the aarch64-apple-darwin have completed successfully)
