Load ONNX Runtime privately per FMU to avoid version collisions (#53) - #55

Conversation
Each FMU now ships its ONNX Runtime library renamed with the model name (e.g. libMyModel_onnxruntime.so) and loads it explicitly at runtime via dlopen/LoadLibraryEx instead of linking against the generic "onnxruntime" name. Previously, two FMUs built by onnx2fmu - or an FMU and an FMI importer that itself embeds ONNX Runtime - could each ship a different ONNX Runtime version under the same library filename; loading both into the same process risked the OS loader resolving to the wrong copy. The model binary's own dependency metadata no longer references ONNX Runtime at all.
