mesa: don't flag _NEW_COLOR for KHR adv.blend if prog constant doesn't change

This only affects drivers that set DriverFlags.NewBlend.

v2: - fix typo advanded -> advanced
    - return "enum gl_advanced_blend_mode" from
      _mesa_get_advanced_blend_sh_constant
    - don't call FLUSH_VERTICES twice
