Introduce new AssistData class that contains all data
the framework automatically generates for assist. Currently
populated with a very simple tree structure representing
the app's view hierarchy.
Reworked how we populate the class name for accessibility
info, so this is provided through a new method call on View
that subclasses can override. This method is also used
to populate the class name in AssistData.

Ensures that delegate code is run last. Previously, calling the super
method from an accessibility delegate set on a widget would only run
code in the widget's parent. Next, the delegate code would run. Finally,
the widget's code would run. As a result, the widget code would override
any data supplied by the delegate.
By moving all overridden code to internal methods, we ensure that the
call chain for super includes the widget's parent code followed by the
widget's code. The delegate code will always run last.

to only framework classes.
AccessibilityEvent and AccessibilityNodeInfo have a property className which is set to the source
Java class. This is problematic since leads to leaking private classes which would allow an
accessibility service to load classes from other packages. This is strongly undesirable since
not trusted code can be loaded, and hence executed, in the accessibility service. To address
that the class name is set to the most concrete framework class extended by the info/event
source.
