AX: Fast-path exit from AXObjectCache::onTextRunsChanged for common renderer
types that will never produce text runs
https://bugs.webkit.org/show_bug.cgi?id=298331
rdar://159772836
Reviewed by Joshua Hoffman.
Also remove the unnecessary AXTextRunsChanged notification and just queue an
isolated tree node update directly. The
notification was a unnecessary abstraction that cost us in performance, since
this notification doesn't actually get
posted out to assistive technologies at the platform level.
