// Currently to know if you need shadow mask you need to go through all visible lights (of CullResult), check the LightBakingOutput struct and look at lightmapBakeType/mixedLightingMode. If one light have shadow mask bake mode, then you need shadow mask features (i.e extra Gbuffer).
// It mean that when we build a standalone player, if we detect a light with bake shadow mask, we generate all shader variant (with and without shadow mask) and at runtime, when a bake shadow mask light is visible, we dynamically allocate an extra GBuffer and switch the shader.
// So the first thing to do is to go through all the light: PrepareLightsForGPU
