This is a follow up to my earlier PRs i particular #2465 and #2482

Originally when the parsing errors were migrated to be structured errors, I didn't make them downcastable (like I did the resolver errors in #2482). This PR fixes that - the errors are now downcastable, instead of being eagerly rendered into strings.
