Allow datetime values in JsonbValue
SQL/JSON standard allows manipulation with datetime values. So, it appears to
be convinient to allow datetime values to be represented in JsonbValue struct.
These datetime values are allowed for temporary representation only. During
serialization datetime values are converted into strings.
SQL/JSON requires writing timestamps with timezone in the same timezone offset
as they were parsed. This is why we allow storage of timezone offset in
JsonbValue struct. For the same reason timezone offset argument is added to
JsonEncodeDateTime() function.
