JIT CI will break with deprecation of x86_64 macOS runners #139153
Description
GitHub is starting random brownouts for macOS runners running under x86_64 arch and it will eventually be deprecated fully.
The https://github.com/python/cpython/blob/main/.github/workflows/jit.yml file will need to be updated to run under rosetta. This, or find alternatives (cirrus-ci, buildbots?)
