CircleCI: change all jobs to M1 (#3140)

`CircleCI` is deprecating Intel machines, so we need to get this
working:
https://discuss.circleci.com/t/macos-intel-support-deprecation-in-january-2024/48718

~~Deadline for this is January 31 2024.~~ New deadline is 28 June 2024.

Note that Codecov isn't compatible
([yet?](codecov/feedback#51)) so I'm turning
it off for now.
