This PR adds passing in `stop_on_entry` to debug configs in debug.json
instead of going through initialization args.
This has two benefits:
1. It's more streamlined to a user since every internal adapter supports
`stop_on_entry` for launch requests and Go's adapter supports it for
attach requests too.
2. It will allow @osiewicz `NewSesssionModal` PR to use this field for
the stop on entry checkbox.
