Get rid of dupe id in DatePicker/useDatePicker (#4085)

* Getting rid of duplicated id present in presentational element

* generate a separate id instead to avoid useField complaining in useDateField

a date field in a datepicker/rangepicker gets the field props removed from it, but we still need to call useField in useDateField which will complain that there isnt a aria labelledby so we still need to pass the field props
