Rollup merge of #128467 - estebank:unsized-args, r=cjgillot 
Detect `*` operator on `!Sized` expression

The suggestion is new:

```
error[E0277]: the size for values of type `str` cannot be known at compilation time
  --> $DIR/unsized-str-in-return-expr-arg-and-local.rs:15:9
   |
LL |     let x = *"";
   |         ^ doesn't have a size known at compile-time
   |
   = help: the trait `Sized` is not implemented for `str`
   = note: all local variables must have a statically known size
   = help: unsized locals are gated as an unstable feature
help: references to `!Sized` types like `&str` are `Sized`; consider not dereferencing the expression
   |
LL -     let x = *"";
LL +     let x = "";
   |
```
