AX: move isIgnored caching to AXObject
https://bugs.webkit.org/show_bug.cgi?id=109322

Reviewed by Chris Fleizach.

There's some benefit to caching accessibilityIsIgnored
(using AXComputedObjectAttributeCache) for more than just
AXRenderObject, so move the caching code to AXObject.

AXObject now has a protected virtual method
computeAccessibilityIsIgnored, and all subclasses
override that instead.

No new tests.
