hickory-resolver: Resolver::lookup() and Resolver::lookup_ip() APIs obscure DNSSEC validation failures

Type: advisorySource: OSV1 source record

When calling `Resolver::lookup()` or `Resolver::lookup_ip()` on a resolver with DNSSEC validation enabled, both methods return `Ok(...)` if DNSSEC validation fails. It is possible but very inconvenient to check the validation status of individual records. These methods should instead return an error when DNSSEC validation determines a response is bogus.
