closes #888, though this is a draft.
I took most of the pattern from the multiple runners instructions in docker docs: https://docs.docker.com/build/ci/github-actions/multi-platform/#distribute-build-across-multiple-runners
I kept a few things that were already here, like using the current cache setup, but separate caches for different platforms now.
We'll see if the first part works, but the push steps should only happen on merge.
