Ensure parsers initiated from DOMParser always complete.
This fixes a panic exposed by https://github.com/servo/servo/pull/32820#discussion_r1713451553. We used to run automated tests with the async tokenizer in the pre-Github CI setup, but that was never ported over. These changes add a new job that can run subsets of the WPT suite with non-default configurations.

CI changes are not tested when triggering try run via labels (running mach try should do it though).
