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. |

I also ensure we don't leak HSTRINGs in GetActivationFactory and fix
up some includes in ScopedComInitializer.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
