Rollup merge of #49162 - tmandry:stabilize-termination-trait, r=nikomatsakis
Stabilize termination_trait, split out termination_trait_test For #48453. First time contribution, so I'd really appreciate any feedback on how this PR can be better. Not sure exactly what kind of documentation update is needed. If there is no PR to update the reference, I can try doing that this week as I have time.
