  AX: AccessibilityRenderObject::computeAccessibilityIsIgnored performs an unnecessary ancestry traversal for RenderTexts

Reviewed by Chris Fleizach and Andres Gonzalez.

AccessibilityRenderObject::computeAccessibilityIsIgnored for RenderTexts traverses the ancestry twice.
We can combine this into one traversal. Also modernizes some nearby code to use dynamicDowncast instead
of is + downcast.
