Add separate on/off ids on manual configured IHC lights (#20253)

* Add support for separate on/off ids on manual configured IHC lights.
This makes it easier to support IHC code units thats relies on being
turned on and off through specific inputs.
Also adds a pulse service (ihc.pulse) that supports sending a short on/off pulse to an IHC input.

* Fix

* Lint fix

* Add on/off id support in switch

* Make pulse async

* Code review fixes
