[Feat] aidge_cmp & dev_mode are now automatically added by the ExportNodeCpp instead of within the operators

[Fix] Add an accumulation_type templated argument for the activation and elemwise kernels (until now, the accumulation type was the output type, causing overflow)

[Hotfix] Set dataformat back to default for dims<2 nodes to avoid errors during memory manager execution
