Populate SpawnMetrics with more metrics in WorkerSpawnRunner

The extra metrics that we'll collect in `SpawnMetrics` (on top of
total time that we already collect):

  * Setup time (e.g., prefetching inputs, setting up sandbox, etc.)

  * Queue time (how long it took to acquire a worker/resources)

  * Execution time of the worker (time between sending a request and
  receiving a response)

  * Time to process outputs

  * Number of inputs

RELNOTES: Collect more performance metrics for worker execution.
