KeyboardTrackingView and KeyboardAccessoryView are bugged on iOS 26

[gentlee]

Description

After upgrading to iOS 26, some strange bugs appeared while using KeyboardTrackingView or KeyboardAccessoryView.

1. When hiding keyboard for the first time with interactive dismiss, a huge bottom margin appears in the inverted FlatList. And tracking view content disappears.
2. When going back to screen while keyboard is opened, input in the tracking view is in the middle of the screen.
3. Custom keyboard (by Yandex) permanently overlaps the input / accessory view from tracking view by several pixels.

Passing manageScrollView={false} to Keyboard.KeyboardTrackingView fixes issue with huge bottom inset, but its children (TextInput) are still blank for the first closing, and it still has issue with overlapping by keyboard.

[gentlee]

Looks like blank tracking view content (but not inset) is fixed by changing intrinsicContentSize of ObservingInputAccessoryViewTemp to:

// New

- (CGSize)intrinsicContentSize
{
    return CGSizeMake(self.bounds.size.width, _height);
}

// Old

- (CGSize)intrinsicContentSize
{
    return CGSizeMake(self.bounds.size.width, _keyboardState == KeyboardStateWillShow || _keyboardState == KeyboardStateWillHide ? 0 : _height);
}
