Michael Fabian 'Xaymar' Dirks 778fc7f3fe encoders/handlers/nvenc: Don't list encoders on unsupported systems
Removes the NVENC entry on systems without an NVIDIA GPU by checking if the library for it can be loaded. If it can't be loaded, it's likely that the user does not have a system with NVENC capabilities - and guaranteed that they can't use the encoder as FFmpeg relies on these libraries.
