Pull request pytorch/pytorch#63414 has changed the operation API so that it now accepts a reference as opposed to a pointer.
This breaks our use case of supporting both nightly versions as well as stable versions with
ORTModule
. To support both versions, we need to add preprocessor checks so that the compiler can compile the cpp extensions using the correct API call based on the torch version.
