[ORL-62] Add baked lightmap support to toon shader

[orels1]

For toon-lit worlds baked lightmap needs to influence the ramp.

I think this could be a special section at the bottom that toggles a variant with lightmapping functionality.

No bakery features would be added at this time though

Adde a pretty basic implementation with support for dominant direction lightmaps
