These are 65 utilities located in frontend-js-aui-web/.../util.js. 73 if counting in Liferay.provide utils. We should rewrite them to vanilla JS and move to frontend-js-web.

This epic should not contain:

1. Utils consisting of DOM manipulation of a specific UI component, to be replaced by Clay.
2. Window interaction utilities, see LPS-101984
3. Form submission utilities, see LPS-101986

This epic should contain all remaining utils. Unused utils should be marked as deprecated in LPS-101575
