Subject: gst-plugins-bad: Local patch to fix UWP debug build

We need to add this via a patch because gstreamer is already tagged.

+Subject: [PATCH] d3d11: Fix debug build on UWP
+
+GstDXGIGetDebugInterface() is unused when targeting UWP. We directly
+call DXGIGetDebugInterface1() in that case.
+
+Fixes build failure:
+
+../gst-libs/gst/d3d11/gstd3d11device.cpp(271): error C2440: '=': cannot convert from 'HRESULT (__cdecl *)(UINT,const IID &,void **)' to 'DXGIGetDebugInterface_t'
+../gst-libs/gst/d3d11/gstd3d11device.cpp(271): note: This conversion requires a reinterpret_cast, a C-style cast or function-style cast
