anv: Use the same re-order mode for streamout as for GS

Browse source 
This makes the vertex order of TRISTRIP and TRISTRIP_ADJ primitves
consistent between XFB output and GS input.  Technically, the Vulkan
spec allows us to XFB out in whatever order we want but being consistent
with GS inputs is probably nicer to apps.
