Auto merge of #17672 - sadmansk:heap_in_box, r=jdm
Use boxed slice instead of vec for FuntionTimerCallback <!-- Please describe your changes on the following line: --> Added `fn trace()` implementation for `Box<[T]>` type, and change FunctionTimerCallback to store boxed slices for heap values instead of Vector. --- <!-- 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 #17611 <!-- Either: --> - [x] These changes do not require tests <!-- 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. --> <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/servo/servo/17672) <!-- Reviewable:end -->
