Update onnxruntime-gpu (#697)

## What does this PR do?

**Type of change:** Bug fix 

**Overview:** Updated setup.py to use only onnxruntime-gpu and removed
onnxruntime-directml as dependency.
Also changed onnxruntime-gpu version in examples.


## Testing
Tested int4 quantization and MMLU benchmark with updated onnxruntime-gpu
, working as expected
