Lightmapper is slow when using "Always Refresh"

Global Illumination

-

The GPU light mapper is not performant when using the "Always Refresh" feature (previously named "animated materials").

It can really tank baking performance on a complex scene, as the GPU will be busy re-rendering the scene constantly.

Suggestion:
- Info message telling the user to turn that off (in the lighting window) or right before starting a bake
- Automatically disable it during baking
- Introduce a "pure bake mode" that just render nothing in the viewport, for maximum baking performance
