Base linking FKs on the same table wouldn't be created in the database, since they are redundant, so we can just remove this

If I remove this, then "Entity_splitting_is_stored_in_snapshot_with_tables" fails. Not sure what the correct behavior should be for entity splitting.

…linking across tables E.g. for TPT. Fixes #28532 (Cascade delete behavior for FK between PKs in TPT) Note this is a breaking change--creating a cascade delete for the TPT relationship could cause a cycle with another existing cascade relationship. This is what happened with the GearsOfWar model.
