Fix: smoke noise tile was saved in Blender executable directory, which is often write protected on modern systems.

This caused high resolution smoke to always regenerate new tile when domain was reinitialized, slowing down especially adaptive domain simulations. Now noise tile is saved in Blender temp directory instead.
