Debugger: Add stop on entry support to debug adapter configs (#27942)

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
