fixes: flutter/flutter#172694 When a merge group is destroyed (for dequeued or invalided reasons), the corresponding content-aware hash build is now explicitly marked as failed. This short-curcuits waiting for LUCI jobs to be canceled. When a content-aware hash build fails, it can now be taken over by a subsequent build for the same content hash. This happens when a PR is removed from the merge queue and an "engine" PR is added back - the previous failure will be restarted and "content_hash" passed to LUCI recipes. The `ContentAwareHashBuilds` model now includes a list of `failedCommitShas` to track the history of failed attempts for a given content hash. When a new build takes over a failed one, the old commit SHA is added to this list.
