Track stats are roughly equal in size as the RTP stream stats which
are the largest objects making up the majority of the RTCStatsReport
size and scales with meeting size. Deleting track/stream reduces the
size in approximately half which should reduce performance overhead
and unblock code simplifications.

Optional better describes "optionality" so let's do it for the sake of
style. But a side-effect of switching to optional may be better memory
locality than std::unique_ptr<>. (Anecdotally I saw a pprof suggesting a
significant amount of time being spent allocating/reading these maps.
This CL is unlikely to make the difference but it can't hurt.)
