Fix automations listening to HOMEASSISTANT_START (#6936)

* Fire EVENT_HOMEASSISTANT_START automations off right away while starting

* Actually have core state be set to 'starting' during boot

* Fix correct start implementation

* Test and deprecate event automation platform on start

* Fix doc strings

* Remove shutting down exception

* More strict when to mark an instance as finished

* Add automation platform to listen for start/shutdown

* When we stop we should wait till it's all done

* Fix testing

* Fix async bugs in tests

* Only set UVLOOP when hass starts from CLI

* This hangs normal asyncio event loop

* Clean up Z-Wave node entity test
