Integrate DownloadForegroundServiceManager.

This is part of the larger refactor to make downloads a foreground
service. The DownloadForegroundServiceManager (DFSM) was created as a
a manager to keep track of which downloads are active/inactive and turn
the DownloadForegroundService (DFS) on/off accordingly. This CL
integrates the previously isolated DFSM/DFS combination so that updates
from native that go through the SystemDownloadNotifier (SDN) propagate
to the DownloadNotificationService (DNS), as it did before, but,
instead of starting the DNS as a service, it notifies the DFSM, which
starts/stops the DFS. This takes out a lot of the service queuing
logic out of the SDN and cleaning up the DNS so to make sure it is no
longer a service (removing summary notification, extends Service, etc.)
