	  Configures the available heap memory pool for ZBus.
	  The heap is used for various ZBus operations (especially required for dynamic buffer allocation for
	  message subscribers and runtime observers).
	  In case of dynamic net buffer allocation the heap must fit all data distributed via message subscribers.
	  Can be set manual, if more heap is required, or default heap size is too big for the soc.
