[AF] Remove cleaned-up flags from flag-metadata.json

Although the code was cleaned up, since the flags were left in
flag-metadata.json, we got alert emails that the flags were going to be
expiring.  To prevent these alarming emails, just remove the cleaned-up
flags.

Also updates some other Autofill-related flags, incl. owners and expiry.
