  Move Objectlabel from Texture object to TextureState object.
  
  Created a subscriber function onLabelUpdated in the storage base
  class. The derived storage class will pass the label reference to
  the base storage class in the constructor. Future changes will use
  this label reference to update the label string with D3D.
