Subject: [PATCH] Load: remove `class-feed.php` (There is no class named `Feed`
 or `WP_Feed`, it just loads other classes) and, instead, move the `require`
 calls to the only place they are ever included: inside `fetch_feed()`. This
 simplifies the include path.

Tested with this feed in a widget: `http://rss.nytimes.com/services/xml/rss/nyt/HomePage.xml`.

See #36335.
