[dnssd] support ANY record type queries (#11447)
This commit updates the DNS-SD `Server` implementation to support queries for the `ANY` record type. This is supported whether a query is resolved using the SRP server or the OpenThread native Discovery Proxy. When a query is resolved using the SRP server database, all known records that match the query name and type are included in the response (e.g., AAAA and KEY records for a hostname; SRV, TXT and KEY records for a service instance name; and PTR records for service type or sub-type query names). Note that unlike mDNS, where an `ANY` query is expected to elicit all known matching records, in the case of a unicast DNS query for `ANY`, the response is only required to contain at least one matching record, not necessarily all of them. This will be the behavior when the Discovery Proxy is used to resolve a unicast DNS `ANY` query (i.e., once the first answer is received from the Discovery Proxy (mDNS), a response is prepared and sent to the client). The unit tests `test_dns_client` and `test_dnssd_discovery_proxy` are updated to validate the new `ANY` query behavior.
