All supported platforms provide 64-bit integer types since many years, so remove the legacy wxLongLongWx implementation and rename wxLongLongNative to just wxLongLong and always compile it in. Note that wxLongLong itself must still be kept for compatibility as it has member functions, such as GetValue() or ToString(), that can be used in the existing code.
