Validate TimeZone in TextClock.setTimeZone
TimeZone.getTimeZone appears to perform less stringent checks
than tz.ToZoneId, which leads to a crash in the widget when we do eventually call toZoneId upon a time tick.
An example of such an invalid timezone is "GMT+20:00".
TextClock is a remotable view, so this leads to crashes in the Launcher process when it's part of a widget.
