 {{{
 #!CommitTicketReference repository="" revision="49865"
 Twenty Twenty-One: Only load IE specific polyfills when actually using
 Internet Exploreer.

 The `twenty-twenty-one-ie11-polyfills` script now has a `null` source, and
 the new `twenty-twenty-one-ie11-polyfills-asset` (which points to the
 actual `polyfills.js` source) will be loaded only if IE is detected by
 through the use of `wp_get_script_polyfill()`.

 Because the original script name remains the same, this change is
 backwards compatible with any code registering `twenty-twenty-one-
 id11-polyfills` as a script dependency.

 Props poena, ismail.elkorchi, peterwilsoncc
 Fixes #52098.
