util: adapt blitter code to new vertex element cso

The interface of util_draw_vertex_buffer looks a bit odd (calling code has to
set vertex elements but not vertex buffers) but due to the way cso state
handling generally works (can't re-bind original vertex element state easily
there) I guess that's ok for now.
