Downgrade xcode

This is a temporary fix for the CI issues that have been plaguing the macOS builders. GitHub updated the default Xcode to 15 in the [2024-02-04](https://github.com/actions/runner-images/releases/tag/macos-13%2F20240204.1) update. This caused two issues to start appearing in CI:

* cmake fails to verify that clang can build a simple test program.
* An `invalid r_symbolnum` linking error when trying to build one of cranelift's tests.

I believe I have a solution for the first problem, but not the second. In the meantime, to help with the CI problems, this PR should temporarily resolve the issue until we have a solution.
