QueryStats for sum of squares execution time overflows its int64_t

      The data in trino is showing integer overflow for metrics_totalexecmicros_sumofsquares_delta.

      Looking at the server code, I can see that this is being calculated in a plain int64, which seems to be inadequate for the values we are seeing in production.
