bpo-5680: IDLE: Customize running a module (GH-13763)

The initialize options are 1) add command line options, which are appended to sys.argv as if passed on a real command line, and 2) skip the shell restart. The customization dialog is accessed by a new entry on the Run menu.
(cherry picked from commit 201bc2d18b60adb05810d2a6ab396047bc527088)
