When Apps recieves a WDOG bite from WCNSS, collecting a register dump of WCNSS is helpful to root cause the failure. WCNSS may not be properly clocked in some WCNSS bite cases, and that may cause unclocked register access failures. So add a feature flag so that customers can disable this register dump on production builds.
