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.
