Since PHP 8.1, `readonly` is a reserved keyword and cannot be used as a function name. In order to avoid PHP parser errors, the `readonly()` function was extracted to a separate file and is now only included conditionally on PHP < 8.1 in WP 5.9. To prevent plugins/themes using this function each having to polyfill it, the new `wp_readonly()` function is being backported.
