fix(windows): don't set window icon on SIGHUP #34260

Problem:  When using conhost and pressing the 'x' button
          to close it while nvim is open, nvim hangs up
          while trying to reset the window icon, causing a big
          delay before the terminal actually closes. #34171

Solution: Set the window handle to NULL after receiving SIGHUP
          so that nvim will not try resetting the icon.
