        Custom handler for the Cloth Component's Mesh Node property as a ComboBoxEditButtonPair widget.

        Handler Name: "MeshNodeSelector"

        Available Attributes:
            EntityId - Entity identifier used to query the mesh asset via MeshComponentRequestBus.
            StringList - List of mesh node names that contain cloth data.

        NOTE: EntityId must be the first attribute set so it's available when consuming StringList.
