AX: aria-describedby text can become stale after the targeted element changes
its subtree

Reviewed by Andres Gonzalez.
When an object targeted by aria-describedby changes its subtree, we need to
re-compute AXPropertyName::{AccessibilityText, ExtendedDescription}
for the described object. We already did this for aria-labelledby
relationships, so this patch hooks into the same
method to check for describedby relationships too.
