AX: accessibilityIsIgnored cache is not enabled at updateChildrenForObjects
level

Reviewed by Tyler Wilcock.
We utilize the AXComputedObjectAttributeCache to cache the isIgnored value of
objects
across certain scopes. Right now, it is enabled in the scope of
AXIsolatedTree::updateChildren.
This patch enables the cache in AXIsolatedTree::updateChildrenForObjects,
allowing all
of the appends downstream to take advantage of the caching. In testing, this
can save
up to 20% of samples of accessibilityIsIgnored.
