Rollup merge of #134265 - compiler-errors:ty_def_id, r=oli-obk

Rename `ty_def_id` so people will stop using it by accident

This function is just for cycle detection, but people keep using it because they think it's the right way of getting the def id from a `Ty` (and I can't blame them necessarily).
