processor: Refactor TimestampedTracePiece

Chrome wants to add a few more counters to TrackEvents, which would
eventually also need a place in TimestampedTracePiece. Since TTP has
been growing a lot (and this contributed to increased memory usage in
trace processor), this patch refactors TimestampedTracePiece to make it
easier to add new data to only a subset of sorted events, while keeping
the TimestampedTracePiece of other events small.

Each TTP now has a type, and each type can store either inline or
heap-allocated supplemental data.
