Rename capture_pre_autograd_graph private method (#6214)

Summary:
Pull Request resolved: #6214

These are mainly no-op changes. The underlying function is already changed.

git grep `capture_pre_autograd_graph` finds these helper functions but in fact we already done migrating.

So let's change the name of the method

This is not going to be cherry-picked, but fixed in main.

+- _torch.export_for_training_: get a graph that is ready for pt2 graph-based quantization.
 - _pt2e_quantize_ with passed in quantizers.
   - util functions in _quantizer_lib.py_ can help to get different quantizers based on the needs.
 - _export_to_edge_: export to edge dialect
