dxgi: Do not create a d3d11 swapchain object for the implicit swapchain.

Browse source 
This swapchain is never actually exposed, and effectively only exists due to
implementation constraints. When it was introduced, it was necessary or simplest
to create a dxgi swapchain object, but currently that's no longer necessary, and
avoiding that allows some code to be simplified.
