Should we maybe provide filters for both of these values (or a single combined one) so that sites can adapt this for optimization or debugging purposes?

Summary
Fixes #4779
This introduces garbage collection for validation data (
amp_validated_urlposts andamp_validation_errorterms).With Site Scanning in v2.2, the most recently-published post will be validated on a weekly basis. If the user never sees the list of Validated URLs—such as when the user doesn't have DevTools turned on—the end result is a perpetual increase in the number of validated URLs. Over time this will result in validation data taking up more and more of the database. When all of the validation errors associated with a validated URL are unreviewed, or if all of the validation errors are related to other validated URLs as well, then there is no need to keep the old validated URLs in perpetuity. They should be garbage-collected.
This PR introduces a new cron task which runs on a daily basis. It obtains a random set of
amp_validated_urlposts that are older than 1 week. For each post which is stale, it checks to see if it has associatedamp_validation_errortaxonomy terms. The validated URL garbage collected if it does not have a unique validation error (not associated with any other URL) which has been been marked as reviewed or has a non-default removed state.After the validated URLs have been garbage-collected, the cron task finally calls
AMP_Validation_Error_Taxonomy::delete_empty_terms()to remove anyamp_validation_errortaxonomy terms which no longer have any associated validated URLs. This is the same action that previously required the user to click the “Clear Empty” button on the Error Index screen:The logic described above prevents deleting validated URLs that would cause validation error terms to become empty unless they are not reviewed and not in the default removed state.
