Event Bridge Scheduler Executor

[eukreign]

EventBridge Scheduler was recently added but without an implementation of actual job execution. This issue is to track the implementation of the job executor.

Previous issue tracking the basic API implementation: #7268 (PR: #8754)

Suggestion for path to implementing this was made in the previous PR:
#8754 (review)

Hey all 👋 ! We are loving localstack so far, but in order to mimic Event Bridges Scheduler execution semantics we have implemented an Event Bridge Rule that ticks every minute using the Event Bridge Scheduler SDK we find schedules that are due and we push them on the target queues.

We would really like to have this implemented in localstack natively. Happy to provide any help on this if needed.
