Instead of communicating with layout via messages, script can simply call methods on the layout trait. This simplifies the way that script communicates with layout and opens the path to sharing more data structures between the two systems. This is part of a continuing series of cleanups after removing the layout thread. <!-- Please describe your changes on the following line: --> --- <!-- 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 they should not change behavior. <!-- 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. -->
