Cargo - Support of object without ace_cargo_size defined in config …

…or `-1` config value (#6364)

* Add: Now findUnloadPosition support also cargo object

- use of ace_cargo_fnc_getSizeItem to determine size of item

- prefer the config way instead of manually set size

- This will also take into account object manually added to the cargo system with ace_cargo_fnc_setsize

- use the cargo object for ace_cargo_fnc_unloadItem.

* FIX: old work around

* FIX: error when cargo module is not loaded

* As suggested by @orbis2358

This fix handle the case when cargo module is not loaded for scheduled and unscheduled environnement.

* Use ACE framework to check if module is present

* FIX: EFUNC and isEqualto

- _itemSize here is always number
- here we are in common module (addons/common/functions/fnc_findUnloadPosition) so FUNC is ace_common_fnc

* FIX case where config value is `-1`

- if the config value is -1, get the `ace_cargo_size` from the `ace_cargo_fnc_getSizeItem
