[IT4.5] Update radio power from CS directly

Browse Source 
There were two ways to update the network activity from
NetworkManagementService to BatteryStatsService.
  1. The Netd unsolicited event onInterfaceClassActivityChanged
  2. The idle timer setup and removal

The first path was replaced by previous patch to listen netd
event from BSS directly. BSS does not rely on NMS to notify
event from netd now.

This patch is going to replace the second path. In order to clear
the dependency between NMS and CS, the idle timer setup and
removal will be sent from CS to INetd directly without going via
NMS in the follow up patches. NMS will no longer receive the
idle timer update. Thus, update the radio power status from CS
to BSS directly to separate the network activity logic from NMS.
