d3d11decoder: Always use render-target bind flag for downstream pool

Browse source 
To convert decoded texture into other format, downstream would use
video processor instead of shader. In order for downstream to
be able to use video processor even if we copied decoded texture
into downstream pool, we should set this bind flag. Otherwise,
downstream would keep switching video processor and shader
to convert format which would result in inconsistent image quality.
