* Fix trait collection handling in ASCollectionElement
- Don't store a trait environment directly and request it when needed. The environment is often the cotaining collection/table node. Asking it for a trait collection is an upward tree traversal and can cause deadlocks. This reverts #2963.
- If the environment changes during a change set update, notify all visible elements about the change. This fixes#2959.
* Address comments
* New way to informing interaction delegate if ASCellNode get’s a setNeedsLayout call
* Remove nodeDidGetNeedsLayout as optional and better check if cell updates need to happen
* Differentiate between letting a normal display node and a cell node know that the size could have changed
* Check for _interactionDelegate is nil
* Add nullability to out pointer
* Adress comments and some renaming
