Working IPv4 & IPv6 DNS resolution for single and multiple hosts

[sjanusz-r7]

This PR adds returning of multiple IPv4 and IPv6 addresses for a single host and multiple hosts. This is thanks to the new TLV group type, TLV_TYPE_RESOLVE_HOST_ENTRY, that comes from the pre-requisite PR here: rapid7/metasploit-framework#18499

I've changed the DWORD resolve_host function to now return the whole addrinfo structure, rather than only a single IP. This means that we now need to call freeaddrinfo() on the result to ensure proper cleanup.

Before

IPv4: Calling irb -e "puts framework.sessions.values.last.net.resolve.resolve_hosts ['google.com', 'bing.com', 'duckduckgo.com', 'cloudflare.com', 'slack.com', 'rapid7.com'], 2"

{:hostname=>"google.com", :ip=>"142.250.102.100", :ips=>["142.250.102.100"]}
{:hostname=>"bing.com", :ip=>"204.79.197.200", :ips=>["204.79.197.200"]}
{:hostname=>"duckduckgo.com", :ip=>"52.142.124.215", :ips=>["52.142.124.215"]}
{:hostname=>"cloudflare.com", :ip=>"104.16.133.229", :ips=>["104.16.133.229"]}
{:hostname=>"slack.com", :ip=>"18.169.120.191", :ips=>["18.169.120.191"]}
{:hostname=>"rapid7.com", :ip=>"108.138.85.72", :ips=>["108.138.85.72"]}

IPv6: Calling irb -e "puts framework.sessions.values.last.net.resolve.resolve_hosts ['localhost', 'mytestdns'], 23"

{:hostname=>"google.com", :ip=>"2a00:1450:4025:402::71", :ips=>["2a00:1450:4025:402::71"]}
{:hostname=>"example.com", :ip=>"2606:2800:220:1:248:1893:25c8:1946", :ips=>["2606:2800:220:1:248:1893:25c8:1946"]}
