This replaces the awkward reuse of encode-time to both convert
calendrical timestamps to Lisp timestamps, and to convert Lisp
timestamps to other forms.  Now, encode-time does just the
former and the new function does just the latter.
The new function builds on a suggestion by Lars Ingebrigtsen in:
https://lists.gnu.org/r/emacs-devel/2019-07/msg00801.html
and refined by Stefan Monnier in:
https://lists.gnu.org/r/emacs-devel/2019-07/msg00803.html

(Fencode_time): Remove argument FORM.  All callers changed.
Do not attempt to encode time values; just encode
decoded (calendrical) times.
Unless CURRENT_TIME_LIST, just return VALUE since HZ is 1.
(Ftime_convert): New function, which does the time value
conversion that bleeding-edge encode-time formerly did.
Return TIME if it is easy to see that it is already
of the correct form.
