Vulkan: add vulkan error code in the error message If driver returns error code that we do not know, we simply output "unknown vulkan error code". Instead we should at least include the actual errorCode here so that people can search up to see what it is. Also remove the double period at the end of string and added a few other vulkan error strings.
