//   Instanceless tests
// Tests of validation of vkCreateInstance and vkDestroyInstance via the pNext debug callback.
//
// This set of test should ideally be as complete as possible. Most of the VUs are Implicit (i.e. automatically generated), but any
// of the parameters could expose a bug or inadequacy in the Loader or the debug extension.
//
// Note: testing pCreateInfo pointer, the sType of a debug struct, the debug callback pointer, the ppEnabledLayerNames pointer, and
//       the ppEnabledExtensionNames would require extenally enabled debug layers, so this is currently not performed.
//
// TODO: VkDebugReportCallbackCreateInfoEXT::flags and VkDebugUtilsMessengerCreateInfoEXT various Flags could theoretically be
//       tested if the debug extensions are made robust enough
