Rollup merge of #62330 - SimonSapin:no-drop-in-union-fields, r=RalfJung
Change untagged_unions to not allow union fields with drop This is a rebase of #56440, massaged to solve merge conflicts and make the test suite pass. Change untagged_unions to not allow union fields with drop Union fields may now never have a type with attached destructor. This for example allows unions to use arbitrary field types only by wrapping them in `ManuallyDrop` (or similar). The stable rule remains, that union fields must be `Copy`. We use the new rule for the `untagged_union` feature. Tracking issue: https://github.com/rust-lang/rust/issues/55149
