Handle the responses in examples

[ArcturusZhang]

Fixes https://github.com/Azure/autorest.csharp/issues/5015

Description

We write response handling in protocol methods by adding Console.WriteLine for all its properties in the response. This PR changes the implementation of constructing those Console.WriteLine to "write a line if the example value of the response is not null"
