Auto merge of #12404 - ConnorGBrewster:task_source_cleanup, r=asajeffrey

Clean up task sources and make all tasks cancellable

<!-- Please describe your changes on the following line: -->
This makes it so each task is a thin wrapper over a runnable and whenever a task is queued, it is automatically wrapped by the window's `runnable_wrapper`.

<!-- 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  #11703 (github issue number if applicable).

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

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