Support for Microsoft.Data.SqlClient

I always use the Nuget Microsoft.Data.SqlClient since it seems better and its Microsoft's recommendation.

When using the ML.NET Model Builder, it uses System.Sql.SqlClient and that should up as an vulnerable dependency.

While I can could just right code myself, I'd like to see the Model Builder use the new technology.

I tried searching the Issues for this particular request, but I didn't see it. So if its a duplicate, it can be closed.
