Add DateRange and smart date Field Support

This has been on our prod site for a few months as a local patch.

Here is a better patch that supports and daterange end value as well. In the webform configuration settings you would have to dates separated by a "/".

I have been running the previous patch in prod for years, but recently switched to the "smart date" module so I updated this patch to handle both the daterange field and the smart date field.

You basically pass the dates start and end dates from the webform like this. With a /slash between the two dates.

[webform_submission:values:start_date_time:html_datetime_short:nolabel]/[webform_submission:values:end_date_time:html_datetime_short:nolabel]
