Script: Change the rest of script to not rely on Deref<str> for DOMString (#39481)
This is part of the future work of implementing LazyDOMString as
outlined in issue #39479.

We use str() method or direct implementations on DOMString for these
methods. We also change some types.
This is independent of https://github.com/servo/servo/pull/39480

Testing: This is essentially just renaming a method and a type and
should not change functionality.
