trace_processor: use sched_process_free instead of _exit

This change modifies trace processor to consider sched_process_free
instead of sched_process_exit when doing lifetime tracking of threads.
This is more correct as events can happen in association with a process
after the main thread emits _exit but not after _free.

This change also adds end timestamp tracking for processes as well
defined as the time as the main thread emitting _free.
