This patch converts the timespec type to timespec64 type for timekeeping_clocktai() function which is used only in the posix-timers.c file, that makes it ready for 2038 issue.

And remove the declaration of timekeeping_clocktai() in kernel/time/timekeeping.h file, cause nothing uses that declaration now, and it would conflict with the inline definition in the include/linux/timekeeping.h file.

Also introduce the clock_get64 callback pointer for the k_clock structure, and convert the timespec type to timespec64 type for the posix_get_tai() function.

Next patch will convert all the timespec/itimerspec to the timespec64/itimerspec64 type for other callbacks of the k_clock structure in the kernel/time/posix-timers.c file.
