zbus: add user-configurable HEAP_MEM_POOL_ADD_SIZE_ZBUS 



Zbus currently does only support default heap sizes.
The configuration option allows to decrease rom-footprint for embedded
applications. Adding the option to ZBus improves its flexibility and
while not increasing its complexity.

Add default of 0 value to compensate for previous cases where
HEAP_MEM_POOL_ADD_SIZE_ZBUS was defined as "".

Consistent naming 'Zbus'/'zbus' to 'ZBus'

	  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.
