Rollup merge of #105188 - compiler-errors:verbose-ty-err, r=TaKO8Ki

Don't elide type information when printing E0308 with `-Zverbose`

When we pass `-Zverbose`, we kinda expect for all `_` to be replaced with more descriptive information, for example --

```
   = note: expected fn pointer `fn(_, u32)`
                 found fn item `fn(_, i32) {foo}`
```

Where `_` is the "identical" part of the fn signatures, now gets rendered as:

```
   = note: expected fn pointer `fn(i32, u32)`
                 found fn item `fn(i32, i32) {foo}`
```
