First attempt at running on darwin aarch64 (#67103)

This PR is a first attempt to get the build to run on an Apple M1 (ARM 64 / aarch64) machine.
I think the changes are mostly reasonable, apart from some hard-coding to use the Azul JVM,
which at the time of writing seems to be the only available JVM. I'll follow up when our preferred
JVM is available.
