Script lookup iframes by frameid

<!-- Please describe your changes on the following line: -->

Lookup iframes by `FrameId` rather than `PipelineId`. This should make lookup much more reliable, since the frame id doesn't change.

<!-- 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

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