[SPARK-23272][SQL] add calendar interval type support to ColumnVector
## What changes were proposed in this pull request?
`ColumnVector` is aimed to support all the data types, but
`CalendarIntervalType` is missing. Actually we do support interval type for
inner fields, e.g. `ColumnarRow`, `ColumnarArray` both supports interval type,
it's weird if we don't support interval type at the top level.
This PR adds the interval type support.
## How was this patch tested?
a new test.
