d3d11: Remove GstD3D11VideoProcessor
There are two separate conversion engines in D3D11, one is generic shader pipeline and the other is vendor implementation dependent post processing object ( via ID3D11VideoProcessor
interface, equivalent to one called VPP
in VA
)
Now two conversion engines are integrated into single GstD3D11Converter
!2697 (merged)
and thus we don't need/want to maintain two conversion objects.
