chardev/char-win-stdio: Pass Ctrl+C to guest with a multiplexed monitor
At present when pressing Ctrl+C from a guest running on QEMU Windows with a multiplexed monitor, e.g.: -serial mon:stdio, QEMU executable just exits. This behavior is inconsistent with the Linux version. Such behavior is caused by unconditionally setting the input mode ENABLE_PROCESSED_INPUT for a console's input buffer. Fix this by testing whether the chardev is allowed to do so.
