Top-level functions in the net package that only read files,
for example LookupPort(...), or LookupIP(host) where host resides
in /etc/hosts, now work on wasip1.
If the application has the ability to create sockets (for example,
when using a sockets extension to WASI preview 1), it's now
possible to do name resolution by passing a custom Dial function
to a Resolver instance.
