[kernel][timer] Replace lk_bigtime_t with lk_time_ns_t
Replace lk_bigtime_t with lk_time_ns_t in preparation for supporting
higher resolution timers. lk_bigtime_t was 64 bits, but stored micro
seconds. Storing nano seconds gives us hundreds of years range and most
hardware has timer ticks shorter than the 1us we could return before.
