st/mesa: add a fallback for clear_with_quad when no vs_layer
Not all drivers can set gl_Layer from VS. Add a fallback that passes the
instance id from VS to GS, and then uses the GS to set the layer.
Tested by adding
quad_buffers |= clear_buffers;
clear_buffers = 0;
to the st_Clear logic, and forcing set_vertex_shader_layered in all
cases. No piglit regressions (on piglits with 'clear' in the name).
