Original change's description:
> Android notification: Introduce ChromeNotification/PendingIntentProvider.
> 
> The Android API didn't expose notification id/tag and the int flags to
> create Notification's PendingIntent, however we need to use these data
> when recording Chrome notification metrics.
> 
> This CL adds wrapper class that contains these data.
> ChromeNotificationBuilder will use these wrapper class in the future to
> force metrics tracking and usage of NotificationManagerProxy.
> 
> Also we setup a new component for notification.
