Only notify track event session observers about their own instance

Currently track event session observers are shared between all track
event data source instances. So when there are two track event data
sources (in different namespaces), each observer will be notified twice.
In Chrome, this breaks an assumption that there can be no concurrent
tracing sessions.

This CL makes session observers only be notified about the data source
for which they were registered.
