AX: Accessibility text stitching should not stitch the disclosure triangle
generated by summary / details (current behavior breaks
accessibility/missing-content-inside-expanded-details.html)

rdar://166338805
Reviewed by Joshua Hoffman.
With this commit, we stop adding the disclosure triangle generated by summary /
details to any stitch group. This was
a side effect of https://commits.webkit.org/303962@main, which added list
marker stitching. As an implementation detail
of rendering, disclosure triangles are generated via RenderListMarker, which is
why that commit introduced the issue.
Fixes accessibility/missing-content-inside-expanded-details.html with
AccessibilityTextStitchingEnabled.
