The structure can represent both year-month and day-time intervals
Add grammar support for standard SQL interval qualifier syntax in preparation for supporting arbitrary precision intervals. Currently, all day-time intervals are evaluated as DAY TO SECOND intervals, while year-month intervals are evaluated as YEAR TO MONTH intervals.

Add support grammar support for arbitrary precision interval qualifiers in preparation for implementing

There's no functional difference from the existing implementation aside changes to parsing and semantic errors when the intervals are not compatible with what we currently support.
