    [zone-stats] Implement collecting per-object-type zone stats · 627b8781

    ... behind --trace-zone-type-stats flag.
    
    Per-object-type statistics requires the following GN args:
      v8_enable_precise_zone_stats = true
      use_rtti = true
    
    When precise zone stats is enabled, the used zone memory value is
    calculated more precisely, in particular it takes into account
    the state of the active segment. By default, the used memory in
    the active segment is not taken into account because of performance
    overhead.
