[FIR] Don't drop directly inherited functions from origins for intersection overrides in intersection scope

```
open class Base<T> {
    fun foo(): T = ...
}

class Derived<T> : Base<T> {
    override fun foo(): T = ...
}
```

In intersection scope of type `Base<T> & Other<R>` we should create
  intersection override based on `Base.foo(): T` and `Derived.foo(): R`
  at the same time, despite the fact that `Derived.foo` actually directly
  overrides `Base.foo`
