Dmitriy Novozhilov 89b98ef784 [FIR2IR] Properly create FIR f/o for lazy IR f/o
```kotlin
interface A {
    fun foo() // (1)
}

interface B : A {
    // f/o fun foo() // (2)
}
```

In previous commits it was forgotten to create new FIR declarations for
  IR fake-overrides, which led to the situation when `IR lazy functions
  of `(1)` and `(2)` both contained fir of function (1) as their base
  declaration

It seems this change fixed some cases from KT-42020
