Dropping the old NStream sub-library

[dreamer-coding]

Fossil XSDK Pull Request

Description

Dropping the old NStream library in favor of the new network library also removed the Winsock2 dependency, as it becomes useless to Io when the network is removed and was only used to handle Windows socket API.

Testing

Same test minus the old network cases for both C and C++.
