Make dlet work like let, not let*

Change `dlet` so that it has binding semantics like `let` because that
is what a user would expect and it allows a corresponding `dlet*` to
be added later should the need arise.  Fortunately the change has no
effect where it is currently used.

* lisp/subr.el (dlet): Work like let.
* lisp/calendar/cal-bahai.el (calendar-bahai-date-string):
* lisp/calendar/cal-coptic.el (calendar-coptic-date-string):
* lisp/calendar/cal-dst.el (calendar-time-zone-daylight-rules)
(calendar-dst-starts, dst-in-effect):
* lisp/calendar/cal-persia.el (calendar-persian-date-string):
* lisp/calendar/calendar.el (calendar-dlet, calendar-generate-month)
(calendar-update-mode-line, calendar-date-string):
* lisp/calendar/diary-lib.el (diary-list-entries-2)
(diary-list-entries, diary-mark-entries-1, diary-sexp-entry)
(diary-remind, diary-font-lock-date-forms, diary-fancy-date-pattern):
* lisp/calendar/holidays.el (holiday-sexp):
* lisp/calendar/icalendar.el (icalendar--convert-float-to-ical):
* lisp/calendar/solar.el (solar-time-string):
* lisp/calendar/todo-mode.el (todo-date-pattern)
(todo-edit-item--header, todo-convert-legacy-date-time)
(todo-read-date):
Rename `calendar-dlet*` to `calendar-dlet` since it uses `dlet`.
