Modify testing to only record validation pass/fail

* Changed unit tests to only record known the validation pass/fail
status
 * errors are output as part of the failure message if the result is
 unexpected
 * can turn off validation for each test individually
* Moved some SPV_KHR_vulkan_memory_model tests to be compiled for Vulkan
