Instrument Service lifecycle events

Added trace events with a 'Binder token' for Service lifecycle
events dispatched from the system_server. We already have equivalent
events with same 'Binder token' on the client side.

This will enable us correlate the dispatch of the Service event with
the handling in the app. Consequently allowing us to bulk anlayze Service
lifecycle event latencies with attribution to a calling process.
