Push ReactContext logic in derived classes (#44026)
Summary: Pull Request resolved: #44026 Changelog: [Android][Removed] Delete ReactContext.initializeWithInstance(). ReactContext now no longer contains legacy react instance methods. Please use BridgeReactInstance instead. Yet another attempt to land this (last one was D55505416). Copy-pasting below the amazing summary from RSNara. ## Context Prior, ReactContext used to implement bridge logic. For bridgeless mode, we created BridgelessReactContext < ReactContext ## Problem This could lead to failures: we could call bridge methods in bridgeless mode. ## Changes Primary change: - Make all the react instance methods inside ReactContext abstract. Secondary changes: Implement react instance methods in concrete subclasses: - **New:** BridgeReactContext: By delegating to CatalystInstance - **New:** ThemedReactContext: By delegating to inner ReactContext - **Unchanged:** BridgelessReactContext: By delegating to ReactHost ## Auxiliary changes This fixes ThemedReactContext in bridgeless mode. **Problem:** Prior, ThemedReactContext's react instance methods did not work in bridgeless mode: ThemedReactContext wasn't initialized in bridgeless mode, so all those methods had undefined behaviour. **Solution:** ThemedReactContext now implements all react instance methods, by just forwarding to the initialized ReactContext it decorates (which has an instance). NOTE: Intentionally not converting `BridgeReactContext` to Kotlin to minimize the risk of these changes.
