[Issue] Load storage polyfill conditionally

This one follows the approach from #27618 which let's us remove loading of storage polyfill so it is only applied for those rare cases when it is not supported. I also reformatted requirejs-config.js keys a bit so it is aligned with other configurations you can find in Magento codebase.

Preconditions (*)

1. Magento version 2.3.5

Steps to reproduce (*)

1. Storage polyfill is only loaded and applied when either localStorage or sessionStorage are not available.

Expected result (*)

Actual result (*)
