radeonsi: enable R600_DEBUG=nir for vertex and fragment shaders
Also, disable geometry and tessellation shaders. Mixing and matching NIR and TGSI shaders should work (and I've tested it for the VS/PS interface), but geometry and tessellation requires VS-as-ES/LS, which isn't implemented yet for NIR. Reviewed-by: Marek Olšák <marek.olsak@amd.com>
