Code Modernization: Rename parameters that use reserved keywords in `phpunit/tests/rest-api/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 the `$object` parameter to `$response_data` in:
* `WP_Test_REST_Attachments_Controller::additional_field_get_callback()`
* `WP_Test_REST_Autosaves_Controller::additional_field_get_callback()`
* `WP_Test_REST_Categories_Controller::additional_field_get_callback()`
* `WP_Test_REST_Comments_Controller::additional_field_get_callback()`
* `WP_Test_REST_Post_Statuses_Controller::additional_field_get_callback()`
* `WP_Test_REST_Post_Types_Controller::additional_field_get_callback()`
* `WP_Test_REST_Posts_Controller::additional_field_get_callback()`
* `WP_Test_REST_Revisions_Controller::additional_field_get_callback()`
* `WP_Test_REST_Tags_Controller::additional_field_get_callback()`
* `WP_Test_REST_Users_Controller::additional_field_get_callback()`
* Amends the `$data` and `$prepared` parameters for consistency in:
* `WP_REST_Controller::add_additional_fields_to_object()`
* `WP_REST_Controller::filter_response_by_context()`
* `rest_filter_response_by_context()`
