Adds VideoStream and relevant resource loaders to migrate external GDNative plugins to GDExtension. Adds a VideoStreamLoader as a specialization of ResourceFormatLoader as ClassDB::is_parent_class is inaccessible from GDExtension currently. Using Object* instead of Ref<T> in order to avoid the refcount bug (godotengine/godot-cpp#652) Also another bug is in ResourceLoader in use on the extension side that requires fixing.
