Emma Anholt 55d788f434 anv/ds: Associate the VkCommandBuffer some anv-only renderstage events. 
This means the perfetto UI will have a non-zero/NULL handle/name in the UI
on these renderstages.  Unfortunately, intel/ds is outside of vulkan so
unless we pull in anv headers, we can't just pass in the anv_cmd_buffer.
This also means it would be much more painful to pass the cmd buffer to
the rest of the events, so they'll still have unset command buffers.
Still, being able to see the name of the command buffer in at least one of
the events should be useful once that's glued together.
