Code Modernization: Rename parameters that use reserved keywords in wp-includes/rest-api/endpoints/class-wp-rest-controller.php.

While using reserved PHP keywords as parameter name labels is allowed, in the context of function calls using named parameters in PHP 8.0+, this will easily lead to confusion. To avoid that, it is recommended not to use reserved keywords as function parameter names.

This commit:
* Renames `$object` to `$data_object` in `WP_REST_Controller::update_additional_fields_for_object()`.
* Includes a minor code layout fix for better readability.
