`KeyboardAvoidingView` shows the keyboard avoiding area even if the keyboard is closed

[QichenZhu]

Description

In the new architecture, if you open the soft keyboard, unmount KeyboardAvoidingView, close the keyboard, and then remount KeyboardAvoidingView, it still assumes the keyboard is open and displays the keyboard avoiding area.

This issue may happen during navigation because the KeyboardAvoidingView can be unmounted when you navigate away and remounted when you navigate back.

Steps to reproduce

1. Build the reproducer with New Arch enabled and run it on iOS.

2. Click Show Keyboard, and ensure the soft keyboard is visible. If not, enable it in the simulator menu: I/O -> Keyboard -> Toggle Software Keyboard.

3. Click Freeze, Hide Keyboard, Unfreeze buttons in sequence.

Expected result: No blank area under the grey section.

Actual result: A blank area appears under the grey section.
