GDScript: Implement get_dependencies()

Browse Source 
The parser and analyzer now track the dependencies of the script and
return the list when the resource loader ask for them.

What is considered a dependency:

- Any `preload()` call.
- The base script this one extends.
- Any identifier, including types, that refers to global scripts.
- Any autoload singleton reference.
