Fix gdscript analyzer error when instantiating EditorPlugins.

Editor code is not instantiable outside of the editor
(1d14c054a1/core/object/class_db.cpp (L369)).
This is fine for editor plugins and the like, but the GDScript analyzer
balks at it, causing F5 runs to fail: #73525.

Instead, we really just want to know if the type is abstract - so add
a new ClassDB method to check that and nothing else.

Update core/object/class_db.cpp
