Auto merge of #11585 - asajeffrey:constellation-avoid-deadlock-during-pipeline-closure, r=larsbergstrom

Avoid deadlock when closing a pipeline.

<!-- Please describe your changes on the following line: -->
At the moment, the constellation blocks on a pipeline during closure. This PR makes pipeline closure asynchronous.

<!-- 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 #11546.
- [X] These changes do not require tests because testing for absence of deadlock is difficult.

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