i#108348 API CHANGE: add IsUTC to css.util.DateTime etc.

Add IsUTC member to:

com.sun.star.util.DateTime
com.sun.star.util.DateTimeRange
com.sun.star.util.Time

Add new stucts with explicit time zones:

com.sun.star.util.DateTimeWithTimezone
com.sun.star.util.DateWithTimezone
com.sun.star.util.TimeWithTimezone

Adapt the sax::Converter to read/write timezones, and fix the unit test.

Everything else just uses default (no time zone), this commit is just
to fix the API.
