I think there is a gap between columnar format and the unsafe row format.
The current `ColumnVector` format looks reasonable for array type, as it puts
the leaf elements together, which is better for compression.
While changing it to binary makes it faster if we need to read an array
from `ColumnVector` and convert it to `ArrayData`, it's really an efficient way
to store arrays in columnar format. Shall we consider updating`UnsafeArrayData`
format?
