Add nvngx.dll and _nvngx.dll to Nvidia proprietary driver package

[samsky72]

Sorry, may be wrong packaging request, but is it possible to add nvngx.dll and _nvngx.dll to proprietary Nvidia driver installation? These dll's is provided by Nvidia in NVIDIA Linux Driver package for wine support.
These dll's required to enable Nvidia DLSS technology, without it Proton ignore DLSS (i.e DLSS settings just grey).

Please find related discussion on SteamOS gitlab.

Just in case, on arch based systems these dlls located by /usr/lib/nvidia/wine/

For reference, they need to be in the directory ./nvidia/wine relative to the libGLX_nvidia.so shared library. Proton uses dlopen and readlink to locate the DLLs.
