Introduce Windows build of Node Problem Detector

[jeremyje]

Changes to the NPD codebase to split out Linux and Windows dependencies.
Simply allows Windows binary outputs, they do not function yet.
This change also introduces new build targets that are easier to allow for different OS/arch versions.
Old targets are kept to remain compatible with the current CI.

First change for #461.
