[issue22240] argparse support for "python -m module" in help

I implemented the logic and adjusted the existing tests to have a fixed program name. I also fixed the build error by changing how zip files are detected. Based on you comment Nick you however even had a different idea. Currently I check if __spec__.__loader__ is a zip loader but if I understood correct you suggest the check if __spec__.__location__ is a proper subdir of sys.argv[0]?

When I have some more time I will check whether mocking works and otherwise checkout test.support.script_helper or making the function accept spec/argv0
