Fix T83915: Subdivision Surface modifier causes visual artifacts in Cycles rendered viewport - CPU and OptiX

Changing the geometry in the current scene caused the primitive offsets for all geometry to
change, but the values would not be updated in all bottom-level BVH structures. Rendering
artifacts and crashes where the result. This fixes that by ensuring all BVH structures are
updated when the primitive offsets change.
