[Feature] Add conditional compilation support for GetTCPInfo

Now there is functionality for conditionally supporting GetTCPInfo
depending on the platform. If the platform supports it, then the client
can call utilities.GetTCPInfo. In the case that the platform does not
support the GetTCPInfo function call, the result is an error of the type
`NotImplemented`.
