Kousuke Saruta 1f8e72f9b1 [SPARK-35749][SPARK-35773][SQL] Parse unit list interval literals as tightest year-month/day-time interval types ... ### What changes were proposed in this pull request? This PR allow the parser to parse unit list interval literals like `'3' day '10' hours '3' seconds` or `'8' years '3' months` as `YearMonthIntervalType` or `DayTimeIntervalType`. ### Why are the changes needed? For ANSI compliance. ### Does this PR introduce _any_ user-facing change? Yes. I noted the following things in the `sql-migration-guide.md`. * Unit list interval literals are parsed as `YearMonthIntervaType` or `DayTimeIntervalType` instead of `CalendarIntervalType`. * `WEEK`, `MILLISECONS`, `MICROSECOND` and `NANOSECOND` are not valid units for unit list interval literals. * Units of year-month and day-time cannot be mixed like `1 YEAR 2 MINUTES`. ### How was this patch tested? New tests and modified tests. Closes #32949 from sarutak/day-time-multi-units.
