Add an ESLint rule to disallow usage of `Liferay.Util.sub`

[kresimir-coko]

With the massive changes coming as part of https://github.com/liferay-frontend/liferay-portal/pull/2762 (and previous PRs) we must make a rule that will not allow devs to use Liferay.Util.sub as a habit. We can call it something like avoid-global-util and add other commonly used global utils to a white/blacklist.
