d1f0251e - Python bindings fix ups in preparation to Sparse Tensor introduction (#7817)

Python bindings fix ups in preparation to Sparse Tensor introduction (#7817) * Fix up constness in pybindings Fix up return argument treatments. Specifically, for all functions that return pointers or references to the members of other pybind registered classes, we want not to copy them, but internally bump up a reference to the hosting class so they do not disappear before the reference to the returned members is re-claimed. This policy is applied by default to def_property and def_readwrite but not to def_readonly and other def methods. See https://pybind11-jagerman.readthedocs.io/en/stable/advanced.html#return-value-policies https://pybind11.readthedocs.io/en/stable/advanced/functions.html#return-value-policies Move OrtValue binding to a separate file Move IOBinding into separate file.
