[expression] Language support for format_date() and to_{date,datetime,time}()

Browse Source 
By default, those expression use the application's locale. The addition of an optional
language parameter allows handling of dates that wouldn't match that default
locale (say for e.g. an English system running QGIS trying to transform a
French-formatted string into a date object).
