eventlog: Add biographical and retainer profiling traces
This patch adds a new eventlog event which indicates the start of
a biographical profiler sample. These are different to normal events as
they also include the timestamp of when the census took place. This is
because the LDV profiler only emits samples at the end of the run.
Now all the different profiling modes emit consumable events to the
eventlog.
