This CL introduces a way to intercept all PendingIntents from
notification with broadcast receivers. In the following CL we will
add metrics recording into those broadcast receivers. This class will
eventually be used in ChromeNotificationBuilder.

Also we introduce a test that uses UIAutomator to actually click on
a notification in test instead of mocking Android notification API.
And verify the BroadcastReceiver interception.
