Add new rcutorture config NOCB01 that enables CONFIG_RCU_LAZY combined with CONFIG_RCU_NOCB_CPU to exercise the lazy callback code paths in the NOCB implementation.
This config exercises lazy callback paths not covered by other configs, including lazy-only wake and lazy defer logic. This config is not added to CFLIST to avoid increasing the default test duration; it can be run explicitly when lazy callback testing is needed.
