Rewrite debugger for Godot 4 support + improved maintainability (#452)

* Significantly rework the debugger to add Godot 4 support.

* Simplify debugger internal message handling and shorten code paths, to enable easier maintenance in the future.

* Streamline debugger configs: almost all fields are now optional, and the debugger should work out-of-the-box in a wider set of situations.

* Add guardrails, error handling, and input prompts to help guide the user to correct usage/configuration.

* Add the following commands:
  *  godotTools.debugger.debugCurrentFile
  *  godotTools.debugger.debugPinnedFile
  *  godotTools.debugger.pinFile
  *  godotTools.debugger.unpinFile
  *  godotTools.debugger.openPinnedFile
