Alan Jeffrey 990fad9b68 servo: Merge #16916 - Added a TopLevelBrowsingContextId type (from asajeffrey:constellation-top-level-browsing-contexts); r=cbrewster
<!-- Please describe your changes on the following line: -->

Added a `TopLevelBrowsingContextId` type, which is a subtype of `BrowsingContextId` that only refers to top-level browsing contexts.

---
<!-- 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 do not require tests because refactoring

<!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.-->

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