[FIR] Don't create synthetic property if getter and property came from the same class

Usually we create synthetic property in java class if there is a property
  from the base kotlin class and getter/setter with a corresponding name
  in the declared scope or one of supertype scopes. But there is a case,
  where the same supertype contains both property and getter:
```
// FILE: Base.kt
open class Base {
    open val b = "O"

    @JvmName("getBJava")
    fun getB() : String = "K"
}

// FILE: Derived.java
public class Derived extends Base {}
```

In this case we shouldn't create synthetic property, because `getB()`
  function is invisible for `Derived` class
