Add a dependency search mode for GDScript parser

- This mode avoids loading any other resource.
- Search for class_name now uses this mode, to avoid loading in the scan
thread.
- Implement get_dependencies() for GDScript loader, now exporting
dependencies only should include the preloaded resources.
