Simplify checkIfTerminal for Windows 

Instead of relying on EnableVirtualTerminalProcessing from
github.com/konsorten/go-windows-terminal-sequences which just calls
GetConsoleMode, sets ENABLE_VIRTUAL_TERMINAL_PROCESSING and calls
SetConsoleMode with the new modified mode, implement it directly inside
checkIfTerminal. This also avoids the duplicate call to GetConsoleMode.
