Log Vulkan loader errors if the instance failed creation on Fuchsia The vulkan loader can output logs to help us debug why instance creation fails. To catch these logs, we need to pass a debug report callback to vkCreateInstance (since the only other debug report callback is set up after the instance is created). Outputting logs is currently only enabled on Fuchsia, since other platforms may have fallbacks and wouldn't want the error logspam.
