[A11y] Simplification -- don't create tree holes for layout updates

When the layout tree changes, invalidate the related a11y subtree
completely.

This removes one more call site for RepairChildrenOfIncludedParent(),
leaving only one caller remaining, which we hope to remove in a
follow-up.

Also fixes a bug, where the descendants of a textarea were missing
a parent.
