Core/SmartAI: implement SMART_ACTION_OVERRIDE_LIGHT and SMART_ACTION_OVERRIDE_WEATHER (#24146)

* Core\SmartAI: implement SMART_ACTION_OVERRIDE_LIGHT and SMART_ACTION_OVERRIDE_WEATHER

* Change the invoker of action to any worldobject

* Revert "Change the invoker of action to any worldobject"

This reverts commit 2e15f7258553b7057c3e8f67c54efc77fb6d75b8.

* Add dbc-validations for new actions

* Use GetBaseObject() instead of Creature* for new actions. Add debug-logging
