Adds the sys_info class and time_zone::get_info(). The code still has a few quirks and has not been optimized for performance yet. The returned sys_info is compared against the output of the zdump tool in the test giving confidence the implementation is correct. Implements parts of: - P0355 Extending <chrono> to Calendars and Time Zones Implements: - LWGXXXX The sys_info range should be affected by save
