[IMP] calendar: start showing attendee state in calendar form view

This commit adds the attendee state in the form view of a calendar event. To
accomplish this, a computed field was added that would get the response status
for the attendee related to the current user that’s accessing the event form
view. If this computed field is falsy, the field is not shown in the form view.
