Move WASI CI over to Arm runners

[brettcannon]

Takes a CI run from about 8:21 to 6:07.

This is a draft until I can verify switching to Arm runners speeds things up; baseline is 8m21s.

Probably its not a big deal, but after this pr WASI job started failing in CPython forks. An example: https://github.com/skirpichev/cpython/actions/runs/19054675947/job/54423101721?pr=1

I did a build restoring the version of WASITIME to 38.0.2 and it succeeded. https://github.com/diegorusso/cpython/actions/runs/19098164627/job/54563276302

Then I ran again with WASITIME to 38.0.3 and it still works:

I'm not sure why it fails in your case.

It's the cache.

The Linux-wasi-sdk-25 cache on your fork is from the 29th (https://github.com/skirpichev/cpython/actions/caches?page=2&query=Linux-wasi-sdk-25), and this PR moved it to ARM on the 30th. Try deleting it and running again.

We could include the architecture in the cache key, but I doubt it's going to change again often, if at all. (Although this is the second time this has come up.)

Thanks, I confirm.

I don't think too much people enable CI in forks. So, we don't risk by invalidating too much caches.
