demos: Adjust vulkaninfo failure cases

For Windows, after vulkaninfo allocates a console, it tries to resize the
console and change the title text.  Failure of either operation was
treated as console icreation failure, which led to vulkaninfo printing
to the console and then closing the console immediately.  Now treating
AllocConsole() failure as console creation failure and ignoring resize and
title text change failures.  With this change, resize failure will not
stop the app from pausing after printing info to the console.
