[SPARK-38018][SQL][3.2] Fix ColumnVectorUtils.populate to handle Cale…

…ndarIntervalType correctly

### What changes were proposed in this pull request?

This is a backport of #35314 to branch 3.2. See that original PR for context.

### Why are the changes needed?

To fix potential correctness issue.

### Does this PR introduce _any_ user-facing change?

No but fix the exiting correctness issue when reading partition column with CalendarInterval type.

### How was this patch tested?

Added unit test in `ColumnVectorSuite.scala`.

Closes #37114 from c21/branch-3.2.
