Raghavan Raman 59dd12042e [nnc] Removed const from all fields in IR. (#62336)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/62336

This PR was generated by removing `const` for all types of nodes in NNC IR, and fixing compilation errors that were the result of this change.

This is the first step in making all NNC mutations in-place.
