In debug builds VulkanInstance::Destroy() was trying to call
vkDestroyDebugReportCallbackEXT and it would DCHECK after a failure to
find that function. That would happen even if Destroy() is called in
after a failed attempt to load Vulkan libs. It doesn't make sense to
DCHECK in that case. Also now vkDestroyDebugReportCallbackEXT() is
called only if debug callbacks were created successfully.
