KT-50862 Unwrap use-site substitution overrides

Use-site substitution override happens in situations like this:

```
interface List<A> { fun get(i: Int): A }

fun take(list: List<String>) {
  list.get(10) // this call
}
```

We want to have those overrides unwrapped, because we don't want
to deal with a different KtSymbol for each possible use-site
