Summary: This replaces the internal core implementation of `setState` with the new `updateStateWithAutorepeat` which is now the only option. In short, `updateStateWithAutorepeat` works as `setState` with the following features: * The state update might be performed several times until it succeeds. * The callback is being called on every retry with actual previous data provided (can be different on every call). * In case of a static value is provided (simple case, not lambda, the only case on Android for now), the same *new*/provided value will be used for all state updates. In this case, the state update cannot fail. * If a callback is provided, the update operation can be canceled via returning `nullptr` from the callback. This diff removes all mentions of the previous state update approach from the core; some other leftovers will be removed separatly. Changelog: [Internal] Fabric-specific internal change.
