Rollup merge of rust-lang#121664 - compiler-errors:adjust-error-yield…

…-lowering, r=spastorino

Adjust error `yield`/`await` lowering

Adjust the lowering of `yield`/`await` outside of their correct scopes so that we no longer make orpan HIR exprs.

Previously, `yield EXPR` would be lowered directly to `hir::TyKind::Error` (which I'll call `<error>`) which means that `EXPR` was not present in the HIR, but now we lower it to `{ EXPR; <error> }` so that `EXPR` is not orphaned.

Fixes rust-lang#121096
