* Removes script from the `wp_print_footer_scripts` action in Twenty Nineteen, Twenty Twenty, and Twenty Twenty-One. * Switches enqueue functions to just register the scripts in Twenty Fifteen, Twenty Sixteen, and Twenty Seventeen. * Rearranges Twenty Seventeen's scripts to connect `twentyseventeenScreenReaderText` with the global script instead of the unused skip link fix. * Updates scripts in Twenty Fifteen and Twenty Sixteen with code from Twenty Seventeen _to run on Internet Explorer only_. Twenty Sixteen needed to keep an adjustment that offsets the toolbar and border. * Removes the script from JS files in Twenty Thirteen and Twenty Fourteen and edits their modified dates. Props sabernhardt, westonruter, joedolson, flixos90, mukesh27. Fixes #54421.
