arm macos + linux by using the upcoming github m1 host

[CGDogan]

• Building for mac is easy
• To build for linux, use docker likewise. manylinux_2010 doesn't have an arm image published but manylinux_2014 does have an arm image
• I propose sticking to v1.2.X for now. If you do update to v3.X, you would need to remove all the previous shared library builds, (because despite the java api for turbojpeg hasn't changed, the internal connection inside turbojpeg between its exposed API and the shared library has changed), hence needing to drop ppc, s390x builds, needing a major version bump for bioformats. But if you compile for 1.2.X, you can add these shared libraries to the current bioformats without needing to remove the old ones, and computers with these old architectures would continue to work.
• You can test this pull request now before GitHub has free public runners (as I do here: https://github.com/CGDogan/libjpeg-turbo-java/actions/runs/7199609084/job/19611649514). On an arm mac with Docker installed, you go to glencoesoftware/libjpeg-turbo-java settings, go to runners, download the macos runner, run config.sh, run ./run.sh, then this pull request will be tested on your computer automatically.

To switch to GitHub public runners (to check (?) is it ready github/roadmap#819), a few little considerations:

• I replaced the expected mkdir build with rm -rf build && mkdir build, because it seems that the github runner on my computer doesn't delete the previous build files!
• We wont't know it now if the build-dependencies step requires some additional dependencies, since they might be already installed on my computer, but that's unlikely.
• Once github has the public runners, I might need to add a workflow step to install docker
