implement interactive terminal for windows

Summary:
Implementation of interactive terminal, that never was implemented for windows.
First we remember console mode and disable `ENABLE_ECHO_INPUT` and `ENABLE_LINE_INPUT` to get input as soon as one or more characters are available. (see [documentation](https://learn.microsoft.com/en-us/windows/console/setconsolemode))
When disabling interactive terminal we simply restore original console mode
