build(docs-infra): remove obsolete ie-polyfills.js (#29926)

Browse Source 
Now that defferential loading it supported by the cli, remove the
obsolete `ie-polyfills.js` (and associated dependencies).

All polyfills in `ie-polyfills.js` are now included in the
[polyfills-es5][1] bundle, except for `classlist.js`, that is only
needed in order to support `NgClass` on SVG elements, which we don't
use.
