console.c: winsize on Windows

* ext/io/console/console.c (console_set_winsize): use handle for
  writing.  GetConsoleScreenBufferInfo seems failing on a handle
  for reading.
* io.c: [DOC] update the example of IO#winsize to use $stdout
  instead of $stdin, which does not work on Windows.  a patch by
  Jan Lelis <mail AT janlelis.de> at [ruby-core:68574].
  [Bug #10986]
