win32: improvements to get_terminal_width_height

- move winansi_get_terminal_width_height from winansi.c to ioctl.c,
  the only caller;
- check both stdout and stderr for a connection to a console;
- omit unnecessary code in get_terminal_width_height (because the
  WIN32 implementation ignores the file descriptor).
