We previously refactor canvas shutdown to account for the fact that they needed to be shutdown in conjunction with the DOM worker reference kept alive by the CanvasManagerChild. Unfortunately if the compositor process crashes, or otherwise the CanvasManagerChild actor is torn down, we also prematurely shutdown the canvas when it would previously fallback to Skia in the content process. This patch abstracts out canvas shutdown into the CanvasShutdownManager which has the owning reference to the ThreadSafeWorkerRef. It corrects a similar bug on the main thread as well for HTMLCanvasElement. Differential Revision: https://phabricator.services.mozilla.com/D204988
