Core/Thread: Fix race condition converting time values to local time

Replace thread-unsafe localtime() http://www.cplusplus.com/reference/ctime/localtime/ with thread-safe portable ACE_OS::localtime_r() .

Core/Timer: Better handle system clock changes

Change IntervalTimer::Reset() behavior to handle system clock changes forward and backward.
This fixes IntervalTimer:.Passed() returning true till it catches up to the new time, triggering the event up to "std::numeric_limits<time_t>::max() / _interval" times.
Fixes https://github.com/TrinityCore/TrinityCore/issues/5816
