[Analysis API FIR] KtFirSymbolDeclarationOverridesProvider: unwrap fake overrides

We should unwrap substitution overrides as they sometimes cannot be
resolved on demand. We already have this in KDoc contract.
```kotlin
class MyClass {
    val prop = object : LazySchemeProcessor<Int, Int>() {
        override fun is<caret>SchemeFile(name: CharSequence) = name != "str"
    }
}

abstract class LazySchemeProcessor<SCHEME : Number, MUTABLE_SCHEME : SCHEME> {
    open fun isSchemeFile(name: CharSequence) = true
}
```
In this case, we will try to resolve fake override in the context of the
anonymous object, and it will fail because we cannot lazily resolve
local declarations as they are a part of the containing declarations
