When using the Voxel Remesh operator, there are two possible sources of crashes currently: * TBB task stealing in nested parallel loops with thread local data * Null dereference of PBVH data when pushing sculpt undo steps To fix the former issue, this commit guards the `threading::parallel_for` internal function with `threading::isolate_task` to prevent possible task stealing and corruption of the thread local data. Additionally, it has the effect of fixing debug asserts inside `array_utils::gather` due to the this task stealing. To fix the latter issue, this commit adds a call to `BKE_sculpt_update_object_for_edit` to ensure that this data is populated.
