Mike d95df29fc0 early return from multithreaded executor (#7521) 
# Objective

- There is a small perf cost for starting the multithreaded executor.

## Solution

- We can skip that cost when there are zero systems in the schedule. Overall not a big perf boost unless there are a lot of empty schedules that are trying to run, but it is something.

Below is a tracy trace of the run_fixed_update_schedule for many_foxes which has zero systems in it. Yellow is main and red is this pr. The time difference between the peaks of the humps is around 15us.
