WordPress/wp-includes/widgets/class-wp-widget-pages.php
Scott Taylor 9b8169bd30 Move widget classes to their own files in wp-includes/widgets:
* `default-widgets.php` now requires all of the individual classes
* Move the functions scattered about this file to `widget-functions.php`, which loads before `default-widgets.php`, which only conditionally loads anyway in `wp_maybe_load_widgets()`, which is hooked on `plugins_loaded` 

See #33413, #23012.
