Let the date picker take a first day of the week and a format

An application that lets each person choose when their week starts and
how dates are written needs the picker to follow that choice rather
than the locale. <x-datepicker> takes week-start, 0 (Sunday) to 6
(Saturday), and format, dd, MM and yyyy each once around one delimiter
(dd.MM.yyyy, dd/MM/yyyy, MM/dd/yyyy, yyyy-MM-dd). They replace what
Intl derives for firstDayOfWeek() and inputFormat(), so the field, the
server-rendered value, the typed-date reader (year first too), the
calendar's columns and weekday header, Home and End, the dialog's text
fields and ranges all follow them. Month and weekday names stay the
locale's, and wire:model still stores Y-m-d. Values that are neither
are ignored, and without the props nothing changes.
