Wraps a ScriptCanvasAsset reference and registers for the individual AssetBus events

The ScriptCanvasAsset Holder contains functionality for activating the ScriptCanvasEntity stored on the reference asset

It also provides the EditContext reflection for opening the asset in the ScriptCanvas Editor via a button
