Feeds: Remove comment feed HTML headers when empty.
Remove the `link[rel=alternate]` element from the HTML header when the comment feeds are disabled. Previously the HTML element was output with an empty `href` attribute. The element is removed if `get_post_comments_feed_link()` returns an empty string or the feed is disabled via the `feed_links_show_comments_feed` filter. Props barryceelen, audrasjb, costdev, rachelbaker, Boniu91. Fixes #54703. Built from https://develop.svn.wordpress.org/trunk@53125 git-svn-id: http://core.svn.wordpress.org/trunk@52714 1a063a9b-81f0-0310-95a4-ce76da25c4cd
