SWPROT-8953: zpc: Use zwave testfrawework for generating mocks

It will fail to generate mocks:

applications/zpc/components/zwave/zwave_transports/s2/s2_inclusion_mock.c

Note that it is possible that libs2 tf is more up to date
than the one from UnifySDK-1.6.

To avoid duplication of it, it would be desirable to maintain
this project in a single place.

For the record if applied alone some tests will/can fail:

The following tests did not run:
        188 - zwave_smartstart_management_test (Disabled)

The following tests FAILED:
          1 - unify_build (Failed)
        160 - zwave_command_class_switch_multilevel_test (Failed)
        201 - binding_cluster_mapper_test (Failed)

So we will have to adjust this in a zpc specific change
