Andrew Dunham ac574d875c prober: add helper function to check all IPs for a DNS hostname ...

This allows us to check all IP addresses (and address families) for a
given DNS hostname while dynamically discovering new IPs and removing
old ones as they're no longer valid.

Also add a testable example that demonstrates how to use it.

Alternative to #11610
Updates tailscale/corp#16367
