🛠 Fix Dropout Inference Issue in OpenVINO ONNX Conversion

🔍 Issue:

While converting an ONNX model with Dropout layers, inference results were incorrect due to improper handling of Dropout during conversion. This issue is reported in #21615.

🔧 Fix Implemented:

• Updated the ONNX model conversion to handle Dropout layers correctly.
• Ensured that inference results are consistent with expected outputs.
• Tested with multiple models to verify accuracy.

✅ Testing & Verification:

• Ran inference using OpenVINO’s inference_engine and verified outputs.
• Compared results with native ONNX inference to confirm correctness.
• Passed all unit tests in model_conversion module.

@thesakshidiggikar code style needs to be fixed at first, I suppose
