metrics: only create one row per group in time_in_state Before this CL, we were accidentally creating many rows per (utid, core_type) because we joined with a table that was grouped by time_in_state_cpu_id (representing a cluster). This meant we got the same core_type label if the cluster was not known from the power profile mapping Fix by introducing an intermediary table which groups to just (utid, core_type). Bug: 190507133 Change-Id: I5f81ba1cfbe00519bb72a449d2cd540f84fd001b
