Added Attribute ReferenceViewer and new entry in GAS Companion combo menu #
This PR adds a new entry in GAS Companion combo menu in level editor toolbar: Open Reference Viewer for Attributes
Upon clicking, a new window opens listing all Gameplay Attributes. Clicking upon an attribute entry will open the reference viewer for that attribute, listing all assets (Gameplay Effects, Actors, etc.) using them.
