Save initial signup information for users to aid in spam prevention (#31852)
This will allow instance admins to view signup pattern patterns for
public instances. It is modelled after discourse, mastodon, and
MediaWiki's approaches.

Note: This has privacy implications, but as the above-stated open-source
projects take this approach, especially MediaWiki, which I have no doubt
looked into this thoroughly, it is likely okay for us, too. However, I
would be appreciative of any feedback on how this could be improved.
