Missing ClassDB member functions bindings

### Godot version

4.3 stable

### godot-cpp version

4.3 stable, f398ebb

### System information

Windows 10 x64

### Issue description

GDExtension version of the ClassDB class is missing the following member functions:
- `set_property_default_value` (required for my use case);
- `add_linked_property`;
- `get_property_list`;
- `get_property_info`;
- `get_linked_properties_info`.

I was unable to find any information about why is it this way. It would be nice to either have those member functions bindings (particularly `set_property_default_value`) or have some sort of information about the reasoning behind the lack of binding.
