cyclic: Integrate cyclic infrastructure into WATCHDOG_RESET

Browse Source 
This patch integrates the main function responsible for calling all
registered cyclic functions cyclic_run() into the common WATCHDOG_RESET
macro. This guarantees that cyclic_run() is executed very often, which
is necessary for the cyclic functions to get scheduled and executed at
their configured periods.

If CONFIG_WATCHDOG is not enabled, only cyclic_run() without calling
watchdog_reset(). This guarantees that the cyclic functionality does not
rely on CONFIG_WATCHDOG being enabled.
