[jdk21u-dev] RFR: 8325194: GHA: Add macOS M1 testing [v4]

Mon Feb 12 10:46:15 UTC 2024

> Now that macOS M1 executors are [available in GitHub actions](https://github.blog/changelog/2024-01-30-github-actions-introducing-the-new-m1-macos-runner-available-to-open-source/) it makes sense to move the build to run on M1 (rather than cross-compiled) and also enable testing on the platform.
