[EventEngine] Make `AresResolver` build compatible with older c-ares versions (#34314)
Tested by changing c-ares to `1.14.0` in Bazel dependency and verify that the `posix_event_engine_test` build. The test would fail though since c-ares versions < `1.16.0` does not come with address sorting capability so the relevant test cases will fail. But this is probably sufficient to make the Cloud C++ CI job pass and unblock the 1.58 release. <!-- If you know who should review your pull request, please assign it to that person, otherwise the pull request would get assigned randomly.
