Introduce MacOSDnsServerAddressStreamProvider which correctly detect all nameserver configuration on MacOS (#9161)
Motivation:

On MacOS it is not really good enough to check /etc/resolv.conf to determine the nameservers to use. We should retrieve the nameservers using the same way as mDNSResponser and chromium does by doing a JNI call.

Modifications:

Add MacOSDnsServerAddressStreamProvider and testcase

Result:

Use correct nameservers by default on MacOS.
