Issue description

EditorInterface::get_selected_paths() (which returns FileSystemDock::get_singleton()->get_selected_paths()) has a design flaw: it returns an array of paths (String), but it doesn't tell if the selected file was selected from the favorites or in the res:// tree.

It makes it possible to select "twice" a file (one favorite, and the same res:// file).

Steps to reproduce

1. Create an EditorScript script that prints EditorInterface.get_selected_paths()
2. Favorite that script in the FileSystem dock.
3. Select both the favorite item and the script in the res:// tree
4. Run the created editor script.
5. See that the array returns the same path twice.
