AudioService: Track client app recording activity

Update RecordActivityMonitor to use events sent from clients
about their recording activity and coalesce them with
configuration update events sent from audioserver (APM). This
allows providing a high-level view on the recording
configurations consistent with client expectations.

For recorders that are managed entrirely on the server side
(AAudio MMAP) all events do contain configs. These recorders
do not have an associated death handler and need to be cleared
on audioserver restart.

Clearing client-managed trackers on audioserver restart is not
needed anymore. Clients will either continue
recording (AudioRecord handles IAudioRecord re-instantation) or
stop recording and notify AudioService about that.
