  D3D11: Enable dirty bits for Framebuffer11.
  
  This patch works using a notification scheme - whenever a Texture or
  Renderbuffer changes in such a way as to recreate its RenderTarget, we
  pass a signal to the Framebuffer to invalidate some internal state.
  Everything is entirely tracked in the Renderer11 layer, and the GL
  layer is left untouched.
  
  A RenderTarget11 now tracks points to which it is bound, and the
  Framebuffer11 is mostly responsible for managing those links.
  
  The three locations where we notify a Framebuffer when its bound
  RenderTargets might be dirty are:
  
   1) RenderTarget11::~RenderTarget
   2) EGLImageD3D::copyToLocalRendertarget
   3) TextureStorage11_2D::useLevelZeroWorkaroundTexture
  
  This patch gives about a 10% score increase in the D3D11 draw call
  benchmark on my system.
