Seungha Yang e8c923ebde d3d11window: Remove hack related to color space selection 
Use input GstVideoColorPrimaries without any special case handling
otherwise rendered image color would be very wrong.

The hack was added to work around an issue that some Intel driver
couldn't handle wide color gamut image without HDR10 metadata, specifically PQ image.
But device capability can be checked via a method added in
https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/1723
so there's no issue now.

Fixes: https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/issues/1175
