AX: Backing object can be destroyed in _accessibilityActivate
https://bugs.webkit.org/show_bug.cgi?id=268997
rdar://122491194
Reviewed by Chris Fleizach.
Calling AccessibilityObject::press() on the backing object is non-trivial, and
could cause
the object to be destroyed, resulting a null dereference in
_accessibilityActivate when
calling `isStaticText`. This patch protects that backing object with a RefPtr.
