Remove the ash::vk stutter

[marc0246]

ash::vk is a module because it's supposed to be imported. It's really hard to look at whatever this was.

I don't see why you think it was supposed to be imported. But I do think this is a good change regardless.

I say that because that's how the crate is designed and how everyone uses it. Instead of writing VkDeviceCreateInfo you write vk::DeviceCreateInfo. That's why the module is called vk and the types inside don't have the Vk prefix. Typing ash::vk every time is too much syntactic salt and there's no reason for it. On the other hand, there is no reason to import the types inside, as it's a flat module with no other modules on the inside, and the sheer number of types that you would need to import. You aren't supposed to import the types inside even if there were no naming conflicts.

Not every crate is designed this way. vulkano for one doesn't have a flat module structure. It's extremely deeply nested in cases. Also, the module names are quite long. You are pretty much forced to import the types. This is IMO a very big deficiency, given as mentioned, the sheer amount of types that you need. Then there are also crates that have everything at the top level, where you aren't meant to import anything, such as wgpu and many linear algebra libraries.
