…ys.executable` is `None` (pythonGH-106464) Prevent `multiprocessing.spawn` from failing to *import* in environments where `sys.executable` is `None`. This regressed in 3.11 with the addition of support for path-like objects in multiprocessing. Adds a test decorator to have tests only run when part of test_multiprocessing_spawn to `_test_multiprocessing.py` so we can start to avoid re-running the same not-global-state specific test in all 3 modes when there is no need. (cherry picked from commit c60df36) Co-authored-by: Gregory P. Smith <greg@krypto.org>
