Use same constant in runtime for unset debug handle

[Gasoonjia]

Stack from ghstack (oldest at bottom):

• Verify intermediate output capturer on exported program #12461
• -> Use same constant in runtime for unset debug handle #12385

In the runtime we have a contant number for unset debug handle. This diff bring that to python env for usage.
