Merge branch 'jc/ci-use-arm64-p4-on-macos'

We replaced deprecated macos-13 with macos-14 image in GitHub
Actions CI, but we forgot that the image is for arm64.  We have
been seeing a lot of test failures ever since.  Switch to arm64
binary for Perforce tests.

* jc/ci-use-arm64-p4-on-macos:
  Use Perforce arm64 binary on macOS CI jobs
