Use correct DLL export declaration for wxLanguageInfoArray

This class is forward declared with WXDLLIMPEXP_FWD_BASE, so it should be
really declated with the matching WXDLLIMPEXP_BASE and not with
WXDLLIMPEXP_CORE used by WX_DECLARE_EXPORTED_OBJARRAY() by default too.

Somehow the mismatch between forward and real declaration doesn't seem to
create any problems, but still fix this for consistency and because it might
explain http://thread.gmane.org/gmane.comp.lib.wxwidgets.general/83980
