External Libraries: Update getID3 to version 1.9.21.
The latest version includes preliminary PHP 8.1 support, as well as a variety of bug fixes. Release notes: https://github.com/JamesHeinrich/getID3/releases/tag/v1.9.21 A full list of changes in this update can be found on GitHub: https://github.com/JamesHeinrich/getID3/compare/v1.9.20...v1.9.21 This commit also includes PHPCS adjustments previously made for a passing PHP Compatibility scan. Follow-up to [47601], [47737], [47902], [48278], [49621], [50714]. Props jrf, SergeyBiryukov. Fixes #54162. Built from https://develop.svn.wordpress.org/trunk@51900 git-svn-id: http://core.svn.wordpress.org/trunk@51493 1a063a9b-81f0-0310-95a4-ce76da25c4cd
