[FIR2IR] Properly calculate the type of delegated function call

```
interface A {
    fun <T> foo(): T
}

class B(val a: A) : A by A {
    generated fun <T'> foo(): T' {
        return a.foo() // <------
    }
}
```

There was a problem that type of generated delegated call used
  an unsubstituted type of the original delegated declaration, which led
  to a situation when (see example) type of call `a.foo()` was not `T'`
  but `T`, which led to incorrect IR and further exceptions on backend

^KT-64284 Obsolete
