Add Linux, Node8, and Node10 to test matrix (#1445)

- Test both Node8 and Node10 on Windows and Linux
- Only test Node8 on MacOS, since the ASP.NET Core 2.1.X templates are incompatible with Node10 on macOS
  - aspnet/Templating#608
- Move Windows build to "Hosted VS2017" pool which has more agents
  - We would rather use the "Hosted" pool, but "npm restore" currently fails on agents in this pool
- Remove "Preview" from Mac pool name
