[iOS] `accessibilityElementsHidden` does not work if the parent view is `accessible`

Description

When a parent view has the accessible prop set, VoiceOver reads all the text nodes and accessibility labels of its children even if one of them has a parent with the accessibilityElementsHidden / aria-hidden prop set.

Steps to reproduce

1. Open the Expo Snack on an iOS device with Expo Go.
2. Enable VoiceOver (triple press on the power button, if enabled in the settings. Otherwise enable it in Settings > Accessibility > VoiceOver).
3. Verify that VoiceOver reads all three lines in both cases when it should only read "First layout" in the second one, like TalkBack on Android does.

Bắt đầu với Expo Snack được liên kết và tái hiện hành vi trên iOS bằng VoiceOver, tập trung vào sự tương tác giữa accessible và accessibilityElementsHidden/aria-hidden. So sánh kết quả với TalkBack trên Android và lần theo phần xử lý khả năng truy cập của React Native iOS có liên quan. Công việc được xem là hoàn tất khi VoiceOver chỉ đọc “First layout” trong khi nội dung lồng nhau bị ẩn, đồng thời giữ nguyên hành vi hiện có của phần tử cha accessible.
