Stub patch

As it turns out, simply stubbing D3DX11CreateThreadPump to return E_NOTIMPL is
enough to get the game to the intro video playback.

Then it fails with GStreamer being unable to decode WMV2. That's worked around
with winetricks ffdshow, and we get in-game.

Only to then run head first into D3DX11CreateTextureFromMemory() aka. Bug#
56659.

Patch attached.
