Subject: [PATCH] [native] Fix KeyboardAvoidingView animation when cross-fade
 animations enabled on iOS

Summary: Fixes [ENG-5919](https://linear.app/comm/issue/ENG-5919/enabling-cross-fade-transitions-on-ios-makes-app-unusable), which is [this React Native issue](https://github.com/facebook/react-native/issues/29974). I took the patch there as inspiration, but there are minimal differences because we have our own `KeyboardAvoidingView` (which lets us skip using `patch-package`).

Test Plan: Confirm that the repro no longer works: open chat, select `ChatInputBar`, swipe back
