[tracing] Add a configurable output stream for perfetto tracing

Add the ability to provide perfetto with an output stream for the JSON
consumer rather than hardcode it. D8 will use this interface exclusively
once the old trace controller is removed.

Also add a test for scope-managed trace events and their duration - this
was leftover from a previous CL.
