Make jsonpath .string() be immutable for datetimes.
Discussion of commit ed055d249 revealed that we don't actually
want jsonpath's .string() method to depend on DateStyle, nor
TimeZone either, because the non-"_tz" jsonpath functions are
supposed to be immutable. Potentially we could allow a TimeZone
dependency in the "_tz" variants, but it seems better to just
uniformly define this method as returning the same string that
jsonb text output would do. That's easier to implement too,
saving a couple dozen lines.
Patch by me, per complaint from Peter Eisentraut. Back-patch
to v17 where this feature came in (in 66ea94e8e). Also
back-patch ed055d249 to provide test cases.
