Twenty Twenty One: Remove Skiplink shim for Internet Explorer.

Browse Source 
No version of Internet Explorer is still supported by WordPress or Microsoft. Usage of Internet Explorer has dropped to about 0.1%.

Follow up to [61628] to also remove JS that fixed skip link behavior for IE. Also remove overlooked contents of `ie-editor.css.map`.

Props sabernhardt, westonruter, joedolson.
Fixes #64590.
Built from https://develop.svn.wordpress.org/trunk@61635
