Relanding this after a build break in a downstream consumer caused a revert. I've removed the include of the windows.graphics.capture.interop header and instead replaced it with an include of windows.graphics.directx.direct3d11.h which is where the IDirect3DDevice data type that we need is declared. Before this was being included transitively through the WGC header, which was a mistake. 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.
