Fix position embeddings for GPT-J and CodeGen (#22069)

Browse Source 
* Revert "[GPT-J] add deprecation warning (#21869)"

This reverts commit fb76994c41.

* Fix position embeddings for GPT-J and CodeGen

* Address review comments from @gante

* Fix "Copied from" comment referencing wrong function

* Fix copy/paste mistake

* Fix training path

* Hopefully make torch.fx happy

* Move position_ids long cast

* Revert "Hopefully make torch.fx happy"

This reverts commit e41a6f4cad3ff441124c7457b19cfb630d4ca025.

* Changes to help with torch.fx tracing

* Linter fix

* Correct position_ids tensor type hint

* Work-around torch.fx tracing issue

* Get the changes to work with torch.fx

* Address review comment from @michaelbenayoun

* Another small adjustment

* Add explanatory comment; small code tidyup
