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. Release Notes: - N/A
