Add full build workflow to check every variation of the project on MacOS

[wmontwe]

This adds a new workflow to run the build command to check all variants of the app. This should help to catch issues early in the process. It uses the MacOS runner to also cover these development machines.

I don't think we should run a full build on every update to a pull request. It takes forever and I think it's unlikely to catch a lot of errors.

Once we have daily builds, we'll get a full build run every day (with changes to the main branch). I don't think it's a problem that we'll then only catch rare issues after the changes have been merged. We can fix the problem the day after the failed daily run.

If we do this on pull request, then we should probably use a matrix strategy to build in parallel. This way the time does not increase. @wmontwe how do you feel about only doing this on main with daily builds? It might have the downside that if there is an issue from a contributor, they might be long gone and we have to deal with the fallout or back out the patch.

We could do this as part of the daily build with an additional workflow trigger to start it on demand. Due to different platforms used to develop the app, there is a risk that failures will enter main unnoticed.

And yes, this new workflow setup is not sofisticated and could be optimized, so it might take less time to execute.

There is also the GitHub feature to create a merge queue that could run a full test suite before merging into main and avoid heavy builds on pull-request updates. See: https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/incorporating-changes-from-a-pull-request/merging-a-pull-request-with-a-merge-queue

The beauty of that approach is that a merge is also validated aggainst the most recent state of main, ensuring that it will work well.

I'm liking the merge queue thing. Let's agree on something in the next team meeting.

Closing in favor of a more sophisticated version
