vk/meta: Partially fix vkCmdCopyBufferToImage for S8_UINT

Create R8_UINT VkAttachmentView and VkImageView for the stencil data.

This fixes a crash, but the pixels in the destination image are still
incorrect. They are not properly tiled.

Fixes crashes in Crucible tests func.miptree.s8-uint.aspect-stencil.* as
of crucible-7471449. Test results improve 'lost' -> 'fail'.
