- [`KT-57462`](https://youtrack.jetbrains.com/issue/KT-57462) Symbol Light Classes: SymbolLightFieldForProperty should retrieve annotations not from KtPropertySymbol, but from the corresponding backing field
- [`KT-54864`](https://youtrack.jetbrains.com/issue/KT-54864) Analysis API: add function to get expect KtSymbol list by actual KtSymbol
