If the monitor or the serial port use STDIO as backend on Windows 11 host,
e.g. -nographic options is used, the monitor or the guest Linux do not
response to arrow keys.
When Windows creates a console, ENABLE_VIRTUAL_PROCESS_INPUT is disabled
by default. Arrow keys cannot be retrieved by ReadFile or ReadConsoleInput
functions.
Add ENABLE_VIRTUAL_PROCESS_INPUT to the flag which is passed to SetConsoleMode,
when opening stdio console.

I think we should set it only when is_console (although that may not make a difference otherwise)
thanks
if (is_console) {
/* set the terminal in raw mode */
