According to Creating a Vulkan logical device in Chapter 1, we should use one queue per family and set its priority to 1.
If the GPU offers multiple queues per family, the current code will use all of them and set their priority to 1. This PR will fix that behaviour by only using one queue per family and setting its priority to 1, as per the book.
