This used to be the mechanism by which D3D11 vs DXVA was created on
windows for hardware accelerated video. Now that DXVA is only being used
in locations where D3D11 isn't (win7, d3d11_disabled_by_workaround,
d3d11_disabled_by_flag), there isn't a point anymore.
By proxy, this also removes the SupportedVideoDecoderConfigMap and just
goes back to using SupportedVideoDecoderConfigs.
