Reduce cloning of FrameState

<!-- Please describe your changes on the following line: -->
This uses `kmerge` from itertools to construct the jsh future and past iterators without having to do a collect/sort. This allows us to reduce cloning of `FrameState`.

<!-- 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
- [ ] These changes fix #__ (github issue number if applicable).

<!-- Either: -->
- [ ] There are tests for these changes OR
- [X] These changes do not require tests because refactoring

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