profiling: reuse interning output tracker in traced_perf

NB: this refactoring slightly changes the points at which the
heapprofd's DumpState checks for the 500k packet chunking limits. I
believe this retains enough calls to |GetCurrentInternedData| to be
fine, but please double-check (in particular, the WriteMap).

The InterningOutputTracker (nee InternState) isn't yet fully untangled
from a couple of heapprofd specifics, looking for advice on how you'd
prefer them resolved.

The perf profiler is now writing StreamingProfilePackets as a
placeholder. Final flush coming soon.
