fix(ext/node): improve node:dns module compatibility (#32704)
## Summary
- Support `--dns-result-order` flag via `NODE_OPTIONS` env var by
parsing it in the node_options binding and making `dnsOrder`
initialization lazy (evaluated at runtime instead of snapshot time)
- Replace `node:punycode` import with `internal/idna` in `dns/promises`
to avoid spurious punycode deprecation warning
- Export `UV_ENOMEM` from uv binding
- Add `DNSException` alias and `ErrorCaptureStackTrace` to
`dnsException` for proper stack frame trimming
- Emit `internal/test/binding` warning on first use
- Handle `--dns-result-order` flag in node compat test runner
Enables 5 additional `node:dns` compatibility tests:
- `test-dns-default-order-ipv6.js`
- `test-dns-default-order-verbatim.js`
- `test-dns-lookup.js`
- `test-dns-lookup-promises.js`
- `test-dns-memory-error.js`
