[glib/win32-enhance-gtimezone: 14/16] Update the gdatetime Test Program for Windows



commit 05f19e0c568757d7fe2a5c34e934ab250cc8d8eb
Author: Chun-wei Fan <fanchunwei src gnome org>

    Update the gdatetime Test Program for Windows
    
    Update the gdatetime test program to make use of the updates that was
    done in gtimezone.c in the previous commit, so that we don't have to
    worry what language version of Windows the tests are being run in, but
    instead be assured that we produce and check for the English-language
    time zone name strings.
    
    Also, instead of testing for "Pacific Standard Time" in
    test_GDAteTime_printf(), use GetDynamicTimeZoneInformation() to get the
    actual time zone string (where the system running the test program is)
    we want to check for, because on Windows the actual result will be
    dependent on which timezone the system running the test program is in.
