Auto merge of #13897 - scotttrinh:dom-webidl, r=jdm

Partial fix for #12415: DOM interfaces

<!-- Please describe your changes on the following line: -->
Fix exposure of DOM interfaces. Only two of the interfaces needed changing and I want someone to double check on `DOMException` (which I left exposed to both `Window` and `Worker`), but I used Firefox's definition as my source since the specs don't lay it out explicitly.

<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: -->
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] These changes fix (partially) #12415  (github issue number if applicable).

<!-- Either: -->
- [X] These changes do not require tests because they only remove code.

<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->
