LPS-50466 - Migrate Users Admin portlet aui-base javascript

Hey Drew,

Attached is an update for https://issues.liferay.com/browse/LPS-50466.

The general idea we've been going by for this part of the migration is to just do stuff that only uses 'aui-base'.  If a script tag uses any other modules as well, we are leaving it alone for now.

If everything looks good you could send it to Rob when you're done.

Let me know if you have any questions.

Thanks!
