Update CoreRT build to use latest .NET CLI and build tools (#3916)

- Pick up latest .NET Core 2.0 CLI and buildtools
- Remove all project.json references and convert everything to msbuild projects
- Stick to vanilla .NET CLI project shape as much as possible. Minimize dependencies on buildtools special behaviors
