Enqueue a new job every 20 step executions (#15068)

To avoid huge workflows to block the worker, we will enqueue a new job
every 20 steps.
This could be more than 20 if there are branches but I think this is
fine, the goal is only to have a limit set.

Also cleaning a bit the code to mark running steps as failed when
workflow fails.

I tested it on a huge workflow:
