  D3D11: Refactor dependent Framebuffer state changes.
  
  Previously, when a state change would cause a Texture to
  recreate its storage specific to D3D11, we would use a
  dependent notification from RenderTarget11 to Framebuffer11
  to re-check internal dirty bits. In this new method, we
  instead set dirty bits on the gl::Frambuffer directly. This
  also means we use fewer internal objects for these
  notifications, because we share the same structures between
  the D3D11 back-end notifications and the top-level notifications
  we use for Robust init and Framebuffer completeness.
  
  This also allows us to get rid of one "if" that we check on
  every draw call in D3D11.
  
  This also introduces a dirty bits guard concept - a shadow
  set of dirty bits that is checked in dependent state changes
  to ensure that extra bits aren't set inside syncState.
  
  This also implements Framebuffer dirty bits for the D3D9
  back-end. This has the side effect of cleaning up the
  "null colorbuffer" D3D9 workaround.
