Reduce number of implicit meta tasks (#84007) (#84045)
This greatly reduces run time on large inventories since meta tasks are
executed in the main process sequentially and just executing them is expensive.

This change avoids running the following implicit meta tasks:
  * ``flush_handlers`` on hosts where no handlers are notified
  * ``noop`` for the linear strategy's lockstep, instead hosts that are
    not executing the current task are just not part of the current host loop

A playbook consiting of two simple plays both running on ~6000 hosts
runs in:
