`setConsoleMode` should do nothing if the handle is not a terminal. The proposed change is [exactly what `golang.org/x/term/IsTerminal()` does on Windows](https://cs.opensource.google/go/x/term/+/6886f2df:term_windows.go).

Windows terminal handling is different than darwin and linux. It needs to have the terminal mode set to enable virtual terminal processing. This allows colors and other things to work.
