  D3D11: Refactor RenderTarget apply into StateManager11.
  
  This is a refactoring patch only, and doesn't change the behaviour.
  The intent is to make it easy to turn on the Framebuffer dirty bits
  in a subsequent patch, once we can cleanly handle textures and
  renderbuffers getting recreated.
