[CUDA] Fix clip operator

[tianleiwu]

Description

The result of Clip op is not expected when min > max for CUDA. This fixes the implementation to align with operator spec: https://onnx.ai/onnx/operators/onnx__Clip.html

Motivation and Context

ONNX backend test failure with onnx 1.18:

python onnx_backend_test_series.py
======================================================================
FAIL: test_clip_min_greater_than_max_cuda (__main__.OnnxBackendNodeModelTest)
