Use pipeline cache to cache onnx node test data. (#16659)

### Description
Use pipeline cache instead of reading data from the image.


### Motivation and Context
1. To reduce the browser dependency of custom image.
2. The onnx node test data is less than 30M and the cache download time
is very short.
