Split by type, otherwise the results are nicely ordered but combined.
Send a DNS query with the specified name and query type, get back a set of InetAddresses with rfc6724 sorting style asynchronously. The answer will be provided asynchronously through the provided Callback.

This is the first part of Happy Eyeballs ordering - which is helpfully useful.
First, the client MUST sort the addresses received up to this point using Destination Address Selection ([RFC6724], Section 6).

@swankjesse Hey, I don't suggest changing your design for a future RFC (HTTPS records), but maybe worth considering how that would fit in, if we want to use the IPv4 and IPv6 address hints, or ALPN, HSTS, or AltSvc flags from the DNS phase. |

Half of this is now in #7157 |

Not any sort of suggested or refined API. But checking out the options for AsyncDns on both Android (DnsResolver on API 29+) and JVM via DoH.
