Similar to #21259, we can cache the result of fetching custom fields for a specific model for the duration of the request. This will avoid redundant calls to e.g. CustomField.objects.get_for_model(Site) for each object in a request. (Currently, custom fields are inspected for each object when its save() method is called.)
