vulkan: add DebugReportLogger
Add DebugReportLogger that can be used during vkCreateInstance and other
commands. Add vulkan::driver::Logger to create a temporary
DebugReportLogger from a dispatchable object. With them, we can log to
debug report by, for example,
Logger(instance).Warn(obj, "failed with %s", err);
