Subject: [PATCH] Themes: Fix fatal error in `load-styles.php`.

Following [56635], a fatal error occurred in `load-styles.php` leading to admin styles not working, because of a `has_filter()` call being added to `get_stylesheet_director()` and `get_template_directory()`.

This changeset adds `has_filter()` to `wp-admin/includes/noop.php` to prevent such errors. The lack of loading the function does not cause any unintended side effects itself.

Props iandunn, adamsilverstein.
Fixes #59417.
See #18298.
