[test] enhance test_dns_client to include addr resolution query (#10766)

Browse Source 
This commit updates `test_dns_client` to validate independent address
resolution queries (in addition to the existing service resolution
tests). Specifically, it adds test cases for `ResolveIp4Address()`
and scenarios where the server responds with an error RCODE.
