Message:

Script Loader: Stop loading polyfills specific to Internet Explorer

This change removes the inline JavaScript attached to the wp-polyfill script responsible for loading polyfill libraries included specifically for Internet Explorer support.

Support for the final version of IE supported in WordPress Core (IE11) was removed in [50784] and will on longer be supported when the next version of WordPress is released.

These scripts are still registered and available to be enqueued, but WordPress will no longer load them by default.

For more information, see ​https://wordpress.org/news/2021/05/dropping-support-for-internet-explorer-11/.

Props youknowriad, gziolo, sergiomdgomes, desrosj.
Fixes #53078.
