d3d11converter: Rewrite conversion object
Rewriting GstD3D11Converter (equivalent to GstVideoConverter) to optimize some conversion path and clean up. * Extract YUV <-> RGB conversion matrix building method to utils. It will be used by other implementation * Use calculated offset values for YCbCr <-> YPbPr conversion instead of hardcoded values * Handle color range adjustment * Move transform matrix building helper function to utils. The method will be used by other elements * Use single constant buffer. Multiple constatne buffer for conversion pipeline is almost pointless * Remove lots of duplicated HLSL code and split pixel shader code path into sampling -> colorspace conversion -> shader output packing * Avoid floating point precision error around UV coordinates * Optimize RGB -> YUV conversion path Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2581>
