subprocess._optim_args_from_interpreter_flags()

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.
