BatteryStats: Introduce Async external stats requests

Instead of calling out to external processes with a blocking IPC,
pass along a Binder on which the external process can pass back
the response. The calling process can then wait for the reply with
a timeout.

This eliminates watchdog restarts of the system_server when an external
process like telephony or bluetooth hangs.
