[PATCH resend] kernelbase: Improve Get{, Dynamic}TimeZoneInformation() performance.

[Akihiro Sagawa]

How do we improve the performance?
___________________

Stellaris calls the above API massively. It suffers on poor performance
of the API after Wine 4.0-rc1.
By caching localized time zone name string, this patch achieves over 50
times better performance compared with the current implementation.
Although the code looks an ugly bit, we need a speed.
