VkSwapchainCreateInfoKHR Valid Usage of the Vulkan specification is partially ignored.

[hikitrbogithub]

The Vulkan specification, mentions the following:

If imageSharingMode is VK_SHARING_MODE_CONCURRENT, queueFamilyIndexCount must be greater than 1

If imageSharingMode is VK_SHARING_MODE_CONCURRENT, each element of pQueueFamilyIndices must be unique and must be less than pQueueFamilyPropertyCount returned by either vkGetPhysicalDeviceQueueFamilyProperties or vkGetPhysicalDeviceQueueFamilyProperties2 for the physicalDevice that was used to create device

Allows for misuse, for example:

• Calling vulkano::swapchain::Swapchain::new with vulkano::sync::SharingMode::Concurrent(std::vec::Vec::new()) as an argument, would break the former requirement.

• Calling vulkano::swapchain::Swapchain::new with vulkano::sync::SharingMode::Concurrent(vec![1, 1]) as an argument, would break the latter requirement.

This has been fixed in #1832.
