Previously, some multi-functions were allocated in a resource scope. This was fine as long as the multi-functions were only needed during the current evaluation of the node tree. However, now cases arise that require the multi-functions to be alive after the modifier is finished. For example, we want to evaluate fields created with geometry nodes outside of geometry nodes. To make this work, `std::shared_ptr` has to be used in a few more places. Realistically, this shouldn't have a noticable impact on performance. If this does become a bottleneck in the future, we can think about ways to make this work without using `shared_ptr` for multi-functions that are only used once.
