delete the supported domain version upper bounds (microsoft#23237)

### Description
<!-- Describe your changes. -->

This PR changes the range of ONNX versions supported by CANN graph
inference to no upper limit (the previous version supports between 8 and
15), because the CANN version is further upgraded to support some
developers' requirements for higher ONNX versions.
### Motivation and Context
<!-- - Why is this change required? What problem does it solve?
- If it fixes an open issue, please link to the issue here. -->
