fix(ext/node): strip trailing dot from SRV target in dns.resolveSrv() (#33578)
- Strips trailing dot from the SRV record `target` field in `querySrv`
and `queryAny` by applying `fqdnToHostname()`, matching Node.js
behavior.
- Enables 2 Node.js compat tests: `parallel/test-dns-resolvesrv.js`,
`parallel/test-dns-resolvesrv-econnrefused.js`
