Christoph M. Becker f06ac9a486 Fix GH-7939: Cannot unserialize IntlTimeZone objects ...

As it is now, `IntlTimeZone`, `IntlCalendar` and `IntlDateFormatter`
and some other intl class instances can be serialized, but the
representation is meaningless, and unserialization yields uninitialized/
unusable objects.  To prevent users from noticing this too late, we deny
serialization of such objects in the first place.

Closes GH-7945.
