Delete videorendererfactory.h and cricket::GdiVideoRenderer.

Ultimately, all of webrtc/media/devices should be deleted, since it is
unused in webrtc and has no unit tests. But for the time being we
need to keep cricket::GtkVideoRenderer since there are a few
applications depending on it.

PTAL. In particular, look at the dropped windows link dependencies in the build
files. I have no idea what they are, but since the windows bot is happy, I guess
they were needed only by the renderer?
