Rollup merge of #84121 - workingjubilee:stabilize-btree-retain, r=dtolnay
Stabilize BTree{Map,Set}::retain
Closes #79025.
FCP concluded here: https://github.com/rust-lang/rust/issues/79025#issuecomment-817201302
This is an approved feature on BTree{Map,Set} to mirror a functionality in Hash{Map,Set}, which has had some adequate testing since its introduction in https://github.com/rust-lang/rust/pull/79026 and doesn't seem to have caused any problems since.
