fix(ext/node): fix dns.lookup result ordering (#26264)

partially unblocks #25470

This PR aligns the resolution of `localhost` hostname to Node.js
behavior.

In Node.js `dns.lookup("localhost", (_, addr) => console.log(addr))`
prints ipv6 address `::1`, but it prints ipv4 address `127.0.0.1` in
Deno. That difference causes some errors in the work of enabling
`createConnection` option in `http.request` (#25470). This PR fixes the
issue by aligning `dns.lookup` behavior to Node.js.

This PR also changes the following behaviors (resolving TODOs):
- `http.createServer` now listens on ipv6 address `[::]` by default on
linux/mac
- `net.createServer` now listens on ipv6 address `[::]` by default on
linux/mac

These changes are also alignments to Node.js behaviors.
