Wraps a ScriptCanvasAsset reference and registers for the individual AssetBus events

for saving, loading and unloading the asset.

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

as well as attempting to open the ScriptCanvasAsset within the ScriptCanvas Editor.

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