d3d11window: Misc code cleanup

Browse source 
* Remove unnecessary upcasting. We are now dealing with C++ class objects
  and don't need explicit C-style casting in C++ world
* Use helper macro IID_PPV_ARGS() everywhere. It will make code
  a little short.
* Use ComPtr smart pointer instead of calling manual IUnknown::Release()
