 {{{
 #!CommitTicketReference repository="" revision="37920"
 Script Loader: Introduce an API to register resource hints.

 Resource hints allow browsers to prefetch specific pages or render them in
 the background to perform DNS lookups or to begin the connection handshake
 (DNS, TCP, TLS) in the background.

 By default, `wp_resource_hints()` prints hints for "s.w.org" (the
 WordPress.org CDN) and for all scripts and styles which are enqueued from
 external hosts.
 Use the `wp_resource_hints` filter to add custom domains and URLs for
 `dns-prefetch`, `preconnect`, `prefetch` or `prerender`.

 Props voldemortensen, swissspidy.
 Fixes #34292.
