Vulkan: Disable logMemoryReportStats if driver extension not exist logMemoryReportCallbacks and logMemoryReportCallbacks features are useful for memory debugging. But they rely on VK_EXT_device_memory_report extension. Right now if this extension is not there and you enable the log, you still see the logs but everything is all zero. This CL will disable the feature and print out warning message if the extension is not supported.
