GameObject The prefab root.
Helper function to find the prefab root of an object (used for picking niceness).
A prefab internally consists of a Prefab object and the list of objects used for the prefab. The Prefab object has a pointer to the root game object and if the prefab is an instance then it also contains a pointer to the asset it was created from and a list of modifications done to the instance.
This checks if the object is part of a prefab, either instance or asset. If so it returns the root game object of the prefab.
