[ETHOSN] Only use mock inference when whole graph is offloaded (#12296)
The mock inference functionality is only supported when the whole
graph is offloaded to the NPU, otherwise it can result in undefined
behaviour. This patch makes sure the mock inference functionality is
not run on test cases where some parts of the graph are not offloaded
to the NPU, while ensuring the module is still built as a sanity check.
