* @brief Test Timer with K_FOREVER period value
*
* Validates initial timer duration, keeping timer period to K_FOREVER.
* Basically, acting as one-shot timer.
* It initializes the timer with k_timer_init(), then starts the timer
* using k_timer_start() with specific initial duration and period as
* zero. Stops the timer using k_timer_stop() and checks for proper
* completion.
