We still allow mesh shader promote constant output to flat, but mesh shader like geometry shader may store multi vertices' varying in a single thread. So mesh shader may store different constant values to different vertices in a single thread, we should not promote this case to flat. I'm not using shader_info.mesh.ms_cross_invocation_output_access because OpenGL does not require IO to have explicit location, so when nir_shader_gather_info is called in OpenGL GLSL compiler to compute ms_cross_invocation_output_access, some implicit output has -1 location which causes ms_cross_invocation_output_access unset for it.
