RFR: 8325194: GHA: Add macOS M1 testing [v3]

[George Adams]

> 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.

George Adams has updated the pull request incrementally with two additional commits since the last revision:

 - fix boot JDK URL
