cmake-gui: Improve interrupt granularity to fix bug 12649.

Instead of enabling interrupt only when a progress or message callback is called, add a new callback specifically for
interrupt.  This new callback is called from GetFatalErrorOccured() so cmake-gui can immediately report interrupt status
instead of calling queuing a call to cmSystemTools::SetFatalErrorOccured() and waiting for the progress or message
callback to be called to process that queued call.
