Revert "Add ability to load CreateDirect3DDeviceFromDXGIDevice from d3d11.dll"

This reverts commit 23f60ebe015cdefd017639d3eb826bf058cae141.

Reason for revert: breaks downstream: create_direct3d_device.h(14,10): fatal error: 'windows.graphics.capture.interop.h' file not found

Original change's description:
> Add ability to load CreateDirect3DDeviceFromDXGIDevice from d3d11.dll
>
> Creating a Direct3D11Device from a DXGIDevice is necessary for the new
> WGC based window capturer. However, the
> CreateDirect3DDeviceFromDXGIDevice API is not available on all
> versions of Windows, which means we have to load this function from
> d3d11.dll at runtime.
>
> You can see how this function will be used in this CL:
> 196624: Finish implementing WGC Window Capturer and add unit tests. |
> https://webrtc-review.googlesource.com/c/src/+/196624
>
> I also ensure we don't leak HSTRINGs in GetActivationFactory and fix
> up some includes in ScopedComInitializer.
