Rollup merge of #100919 - sanxiyn:parallel-liveness, r=oli-obk

Use par_body_owners for liveness

I did this refactoring while working on something else. Liveness is about bodies, there is no reason to use par_for_each_module here.

Tests are updated because things are visited in a different order. I checked diagnostics are same, just in a different (and IMO, better) order.
