[PATCH v2 1/4] advapi32/tests: Check that registry time zone records have a display name.

[Giovanni Mascellani]

While the display name is not a member of TIME_ZONE_INFORMATION, it is
still available in the registry. In English it corresponds to the
comments preceding groups of time zones in Unicode CLDR's
windowsZones.xml[1].

 [1] https://github.com/unicode-org/cldr/blob/master/common/supplemental/windowsZones.xml

Windows UI shows the display name in the time zone selection control
panel.
