AX: Add accessibility support for details element on iOS
https://bugs.webkit.org/show_bug.cgi?id=162041
Reviewed by Chris Fleizach.
Source/WebCore:
The details and summary elements are poorly supported on iOS.
Two major issues:
1. Assistive technologies taking focus onto details/summary elements will cause unexpected behavior.
2. VoiceOver is not speaking the expanded status of the details element.
Fixed them by not setting focus onto elements inside details and exposing the details element's expanded
status to its summary's accessible children.
