  Vulkan: Restore CommandBuffer to namespace vk
  
  Moved vk::CommandBuffer and vk::SecondaryCommandBuffer to vk::priv:: and
  aliased vk::CommandBuffer to one or the other.  This allows the rest of
  the classes to continue seeing vk::CommandBuffer as they used to do.
  Used a special alias for the primary command buffer that gets submitted
  (vk::PrimaryCommandBuffer).
