Rollup merge of #103386 - compiler-errors:no-coerceunsized-to-dynstar, r=eholk
Don't allow `CoerceUnsized` into `dyn*` (except for trait upcasting) This makes sure we don't accidentally allow coercions like `Box<T>` -> `Box<dyn* Trait>`, or in the case of this ICE, `&T` to `&dyn* Trait`. These coercions don't make sense, at least not via the `CoerceUnsized` trait. Fixes #102172 Fixes #102429
