Propogate status setting for profiler to track parents

[Reland: https://src.chromium.org/viewvc/chrome?view=rev&revision=120789
with minor change to avoid race on status change.]

This allows child processes to track ancestry, and report
it to the browser process.

Parent tracking is only turned on based on an 
environment variable.
