Turn off sharing for D3D11VideoDecoder with swap chains.

Previously, we checked only the finch flag for swap chain support,
in order to turn off resource sharing.  This was intended to avoid
a bug on intel platforms.

This CL replaces the finch check with a more robust one, to match
what dxva does.
