Initial Implementation of Download Notification

This is the first implementation of Download Notification for ChromeOS.
This feature is behind a flag and disabled by default as for now.

The major changes of the patch are:
- Add DownloadNotificationManager, which replaces
    DefaultUIControllerDelegate
- Add DownloadNotificationItem, which represents each  notification
- Add DownloadCommands, which is extracted from
    DownloadShelfContextMenu::ContextMenuCommands
- Rename DefaultUIControllerDelegate ->
    DownloadShelfUIControllerDelegate
- Rename: DefaultUIControllerDelegateAndroid ->
    AndroidUIControllerDelegate
