Enable local action execution statistics collection when the LocalSpawnRunner uses the process-wrapper to run commands.

In particular, record metrics for user and system CPU execution time, block I/O and involuntary context switches.

This feature is guarded behind a new option, --experimental_collect_local_action_metrics.

RELNOTES: None.
