### Bugs fixed
- Queue family count isn't being set in either `ash::vk::BufferCreateInfo` or `ash::vk::ImageCreateInfo`

In either case of buffers or images, the bug occurred when using more than 1 queue family (not exclusive use). queue_family_index_count in the ash structs was not being explicitly set and was left as Default::default(), which is 0, making it in violation of the Vulkan spec (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-VkBufferCreateInfo-sharingMode-00914, https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-VkImageCreateInfo-sharingMode-00942) and potentially causing undefined behavior.
