modify model to enable loading by blob (#31507)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/31507
This script is used to generate a model with bound shape inference and
blob reorder, which are requirements for big model loading on T17.
1. Load existing model.
2. Do bound shape inference and blob reorder (put embedding blobs at the end).
3. Save the modified model.
Test Plan:
Generated a new moel and tested on NNPI.
