Fix T97835: crash when creating hair particle system on Mac

Recently `gpu_shader_3D_smooth_color_frag.glsl` had the uniform declarations removed.

For shaders without `ShaderCreateInfo` that require this source this results in the error:
```
ERROR (gpu.shader): hair_refine_shader_transform_feedback_workaround_create FragShader:
      |
   54 |   fragColor = finalColor;
      |
      | gpu_shader_3D_smooth_color_frag.glsl:5:0: Error: Use of undeclared identifier 'fragColor'
      | gpu_shader_3D_smooth_color_frag.glsl:5:0: Error: Use of undeclared identifier 'finalColor'
      |
   55 |   fragColor = blender_srgb_to_framebuffer_space(fragColor);
      |
      | gpu_shader_3D_smooth_color_frag.glsl:6:0: Error: Use of undeclared identifier 'fragColor'
      | gpu_shader_3D_smooth_color_frag.glsl:6:0: Error: Use of undeclared identifier 'fragColor'
```

So port that shader to use `ShaderCreateInfo`.
