Subject: [PATCH] turnip: build drm_msm_gem_submit_bo array directly

Build drm_msm_gem_submit_bo array directly in tu_bo_list.  We might
change this again, but this is good enough for now.

There are other issues as well, such as not using
VkAllocationCallbacks and sloppy error checking.  We should revisit
this in the near future.  Same to tu_cs.
