TODO(wxy) in core/domain/object_registry.py: Cache this as it is accessed many times.

Improve the performance of ‘get_default_object_values’ by caching results. The function ‘get_default_object_values’ retrieves default object values from a JSON file. However, this method is called frequently, and caching the results is necessary to reduce unnecessary function calls.

Closing because this doesn't follow expected issue-filing conventions.
