This CL is an follow-up to: crrev.com/c/2552897

In this CL we add on to the event suppression logic for events
of TYPE_WINDOW_CONTENT_CHANGED type on Android.

With this CL we move the logic into web_contents_accessibility_android,
and we add unit tests. We include a VisibleForTesting method in
WebContentsAccessibilityImpl that allows us to change the
suppression threshold as needed.
