[PATCH 1/2] winnls.h: Add useless element GEOCLASS_ALL to enum SYSGEOCLASS.

[João Diogo Ferreira]

This is a seemingly useless value that's available since Windows 8,
according to MSDN. I took its value from mingw-w64, and they define it as 0.
All the Windows functions that I've tested fail when called with this argument.

Nevertheless, it remains a (technically) valid argument to be used with a few
functions, such as GetUserGeoID. So I decided to add this case to WineTest,
so we can be sure that it remains a useless value indeed :)

For this reason, I added this value to Wine's headers.
