Nanite cast shadows from all lights, regardless of lighting channel configuration

This behavior is inconsistent with the behavior of non-nanite meshes, which receive light and cast shadows only from lights in the same lighting channel.

1. Create an empty level
2. To that empty level add a non-Nanite mesh, and place a Nanite mesh in front of it
3. Set the Non-nanite mesh to Lighting Channel 1 only
4. Create a new spot light, and set it to Lighting Channel 1 only
5. Point the light at the nanite mesh
6. Observe that the nanite mesh is casting shadows from the spotlight onto the non-nanite mesh behind it
