Code Modernization: Rename parameters that use reserved keywords in wp-includes/functions.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 `$class` parameter to `$class_name` in `_deprecated_class()`.

Follow-up to [54929], [56467].

Props jrf.
See #59161.
