[ONNX] Fix new_full and full_like for Python 3.9 (#67124) (#67806)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/67806
Previously new_full would fail with errors like:
`TypeError: only integer tensors of a single element can be converted to an index`
And full_like would trigger warnings like:
`DeprecationWarning: an integer is required (got type float). Implicit conversion to integers using __int__ is deprecated, and may be removed in a future version of Python.`
