  Vulkan: fix non-float clear with draw
  
  Instead of using one draw call that clears all attachments, multiple
  draw calls are issued that clear a single attachment each.  This allows
  us to have a manageable number of variations for the ImageClear.frag
  shader, now that non-float format support is introduced.
