Issue #26100:

* Add subprocess._optim_args_from_interpreter_flags()
* Add test.support.optim_args_from_interpreter_flags()
* Use new functions in distutils, test_cmd_line_script, test_compileall and
  test_inspect

The change enables test_details() test of test_inspect when -O or -OO command
line option is used.

Issue #26101: Exclude Lib/test/ from sys.path in test_compilepath(). The
directory contains invalid Python files like Lib/test/badsyntax_pep3120.py,
whereas the test ensures that all files can be compiled.
