Reduce test noise by fixing or catching and testing stderr messages from individual tests.
test_cmd_line_script.test_script_as_dev_fd calls spawn_python and hence subprocess.Popen with incompatible arguments. On POSIX, pass_fds forces close_fds to be True (subprocess.py line 848). Correct the call.
test_uuid.test_cli_namespace_required_for_uuid3: when the namespace is omitted, uuid.main calls argparse.Argument_Parser.error, which prints to stderr before calling sys.exit, which raises SystemExit. Unittest assertRaises catches the exception but not the previous output. Catch the output and test it.
test_warnings.test_catchwarnings_with_simplefilter_error similarly prints before raising. Catch the output and test it.

gh-90876: Restore the ability to import multiprocessing when `sys.executable` is `None` (GH-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.

This ensures that `commoninstall` is completed before `bininstall` is
started when parallel builds are used (`make -j install`), and so the
`python3` symlink is only installed after all standard library modules
are installed.
