enable tests on windows and macos ci platform

enable ci/tests.sh to run on ci for windows and macos

This has been partially solved with #609, we still do not test cross with these images.

We should test every image we produce with Linux, Mac and Windows GHA runners.

we still do not test cross with these images.

We don't have images for these targets, so what is there to test?

[Emilgardis]

We do, don't we? https://github.com/cross-rs/cross/pkgs/container/x86_64-pc-windows-gnu

As for testing, I mean tests to catch stuff like #461

[Emilgardis]

I'm struggling with coming up with a satisfactory way to solve this.

Alt 1.

Artifact all images in docker-images and in a new action image-tests step that needs docker-images get all image artifacts, try a subset of those artifacts on windows, linux and macos on some example workspaces, and then on success run publish step which publishes the artifacted images etc.

Alt 2.

run scheduled task that tests current main images with windows/mac/linux on some example workspaces.

We could test for a single platform on macOS and Windows, build a single image fetched from cache (choose one unlikely to change for the best performance) and just install the latest cross and run from our cache?

We don't provide images for *-msvc or *-apple-*, so I think just testing CI works for an image we support on Windows and macOS is a good idea?

[Emilgardis]

That should work, there is one thing to be careful of then however, changes that break mac/windows won't be catched if the conditions needed to break are not in the cached image.

At least we'll catch them relatively early with the weekly update, so we can triage pretty quickly.

this will have to be implemented on self-hosted runners, see actions/runner-images#252 and actions/runner-images#2150
