Previously, the Constellation would immediately ask the Compositor to shut down a pipeline, even before the ScriptThread finished shutting it down. This meant that the Compositor might remove a Pipeline and then re-add it if the ScriptThread sent a Pipeline-related message (such as a new display list) in the meantime. This change makes it so that the Compositor waits for both the Constellation and the ScriptThread to finish shutting down a Pipeline before removing its data. In addition, the Constellation no longer synchronously waits on the Compositor when shutting down Pipelines. This was important when the Compositor would talk to the ScriptThread directly, but isn't necessary any longer. Testing: This is very hard to test, because it depends on the creation and destruction of many iframes and the particular timing of of all the messaging between Servo bits. That said, this was tested manually by observing the completion of Speedometer 2.1. Fixes: #37458.
