Use debug utils during instance creation

[jherico]

The VulkanDebug.h header is referencing the old VK_EXT_debug_report message callback signature, which no longer exists. I've updated the declaration to match the VK_EXT_debug_utils signature and changed the name in VulkanDebug.cpp to match.

Additionally, if validation is enabled, it should be applied to instance creation as well as everything after that. This is allowed by VK_EXT_debug_utils by passing the VkDebugUtilsMessengerCreateInfoEXT structure in the pNext chain of the VkInstanceCreateInfo structure, which the base example code now does.
