Note
There's no open issue/proposal for this AFAIK; I've based on this comment on #98379 (comment) that this was a desired feature
This adds support for debugging multiple threads through DAP, bringing feature parity with #76582.

Note
This includes some misc changes ranging from code cleanups to fixing bad behaviors from the spec. If desired, I can separate them in other dependent PRs
Warning
This implementation is not perfect, and some issues/odd behaviors are coming from Godot itself. This serves as a first implementation, but subsequent work is planned to make multi-thread debugging more robust, both from Godot and DAP.
