fix: switch between inputs with KeyboardGestureArea on iOS

[kirillzyusko]

📜 Description

Fixed a problem with autoclosing keyboard if you switch between inputs + KeyboardGestureArea has active offset.

💡 Motivation and Context

The key problem here is that in previous implementation resignFirstResponder call gets delayed, so first of all we call becomeFirstResponder, then we call resignFirstResponder, but it's getting delayed, so new input get focus and then we call resignFirstResponder and keyboard gets closed.

First fix that I did was saving pending request in resignFirstResponder - I found out that it's getting called two times, and I thought if we call it second time and we have pending request -> we can immediately remove focus and cancel previous task. It works on simulator, but not on a real device - on a real device keyboard becomes hidden and then becomes visible.

To fix all problems I decided to intercept becomeFirstResponder event, and save new focused input. If resignFirstResponder is getting called and we have a pending request, then we should remove inputAccessoryView immediately + don't add any delays. In its turn becomeFirstResponder should store new focus request only for short amount of time - otherwise, if we store it permanently we can not distinguish a case "focus switch" vs "dismiss a keyboard", so current algorithm looks like:

• we have resignFistResponder and in the past frame we had becomeFirstResponder request -> we switch focus, so do a cleanup immediately;
• we have resignFistResponder and in the past frame we didn't have becomeFirstResponder request -> remove inputAccessoryView and close the keyboard (similar to how it was working before).

📢 Changelog

iOS

• swizzle becomeFirstResponder;
• store current first responder for one frame;
• check in resignFirstResponder presence of current first responder and if we have it -> do a cleanup immediately.

🤔 How Has This Been Tested?

Tested manually on iPhone 11 (iOS 17.4), with following code added before ScrollView:

      <AnimatedTextInput
        multiline
        nativeID="chat-input"
        style={{width: "100%", height: 50, backgroundColor: "blue"}}
        testID="chat.input"
      />
