     * This code handles some quirks of FIR sources and PSI:
     * - in `vararg args: String` declaration, `String` type reference has fake source, but `Array<String>` has real source
     * (see [KtFakeSourceElementKind.ArrayTypeFromVarargParameter]).
     * - if FIR reference points to the type with generic parameters (like `Foo<Bar>`), its source is not [KtTypeReference], but
