  [Site Isolation] Fix `WKAccessibilityRootObject`
rdar://132428902
https://bugs.webkit.org/show_bug.cgi?id=277028

Reviewed by Alex Christensen.

`WKAccessibilityRootObject` tries to get the root AX object on the main frame's document, which won't
work if the main frame is out-of-process. Add `_WKAccessibilityRootObject` to get the root AX object
from the frame that is calling `accessibleElementById`.
