Add a flag to the OpenCLZone indicating whether we are performing the first-start OpenCL functionality verification, so that if we run into a crash that is caught by the VCL VCLExceptionSignal_impl() handler, we terminate the process with the EXITHELPER_NORMAL_RESTART status after first having disabled OpenCL use. The wrapper process will then restart soffice.bin. This is for Windows only so far. This matches what we do if OpenGL fails early during start of LibreOffice.
