Subject: [PATCH v2 04/15] posix timers:Introduce the 64bit methods with timespec64 type for k_clock structure

This patch introduces the new methods with timespec64/itimerspec64 type for k_clcok
structure,converts the timepsec type to timespec64 type in k_clock structure and
converts the itimerspec type to itimerspec64 type to ready for 2038 issue.
