Add date time format utilities

See merge request gitlab-org/gitlab!68294

This adds a few date time formatting utils to be used in the DAST
on-demand scans scheduling options.

* isoDateToSameLocaleDate will be used to reset the date and time inputs
  to the correct values when initializing the form with a stored
  datetime and timezone.
* dateAndTimeToUTCString will let us compute a Date instance based on a
  Date generated by a datepicker and a time string from a time input.
* dateToTimeInputValue will serve to restore a time input's value from a
  Date instance.
