Resolves: tdf#126342 obtain date particle order from pattern match

... if there was any. In the NF_EVALDATEFORMAT_FORMAT_INTL case
the input may match a current locale's pattern instead of a
format's locale's pattern and patterns' (format locale + current
locale) date orders may be different from the format's date order.
