Previously shared memory buffers for DesktopCapturer were created using DesktopCapturer::Callback::CreateSharedBuffer(). That made it difficult to proxy DesktopCapturer interface from one thread to another. This CL adds SharedBufferFactory interface that's allowed to be called on a background thread. This also simplifies clients that don't need to use shared memory, as they no longer need to override CreateSharedBuffer().
