fix: schedule missing layout animations

[kirillzyusko]

📜 Description

Schedule layout animations on before keyboard appear/disappear.

💡 Motivation and Context

Looks like after RN 0.71 the disappear animation happens instantly if user pressed on the ScrollView. I don't know what was exactly broken, but I discovered, that if we schedule LayoutAnimation with keyboard type, then animation happens as it should.

So in this PR I decided to schedule layout animations manually and remove them when keyboard finished its movement.

Theoretically it's a little bit dangerous to schedule global animations, but:

• on iOS they are already kind of getting scheduled;
• we remove our animation after keyboard movement completed.

So it's kind of relatively safe 🙃

Closes https://github.com/kirillzyusko/react-native-keyboard-controller/issues/307

📢 Changelog

JS

• added reanimated chat flat list example to Fabric project;

iOS

• added scheduleKeyboardAnimation/unscheduleKeyboardAnimation methods to RCTUIManager (as extension);
• added onRequestAnimation/onCancelAnimation methods to KeyboardMovementObserver;
• call onRequestAnimation on keyboardWill events and onCancelAnimation on keyboardDid events;

🤔 How Has This Been Tested?

Tested on iPhone 15 Pro (both paper and fabric).
