[TIMEDATE.CPL][SYSSETUP][TZLIB] Introduce a small static library "tzlib": "TimeZone Utilities Library", and use it in timedate.cpl and syssetup.dll.

Browse source 
This small win32 library provides time-zone utility wrappers around
Win32 functions, that are used by different ReactOS modules such as
timedate.cpl, syssetup.dll, and a possible future 'tzutil' tool.

The code has been extracted from the common code found in both
timedate.cpl and syssetup.dll.
