Ensure columns have valid null counts.
d51f0f4 
This is in prep for rapidsai/cudf#11968 and
rapidsai/cudf#13372.

`libcudf` will soon require that all CUDF columns are created with a
known null-count. `UNKNOWN_NULL_COUNT` will no longer be supported,
or even available as a code constant.

This change replicates part of rapidsai/cudf#13355,
as it applies to `row_conversion.cu`. The (single) reference to
the unknown-null-count is replaced with a pre-calculated value.

There are a couple of Java failures left that I can reproduce locally. Will attempt to debug them myself, but may need to pull in some advice.

I'm blocking merging here until we've had a chance to check on the behavior of the Spark plugin with this change, but it is otherwise ready for review.

I'm +1 on the JNI changes.

Note that spark-rapids does not depend on this code. row_conversion.cu will be removed as part of #13374. The splash damage here should be limited.

Followup for null count fixup in row_conversion.cu.
48eb6e2 
This is a followup to NVIDIA#1148.

`row_conversion.cu` was modified in rapidsai/cudf#13372
to explicitly calculate null-counts for output columns.

This commit replicates the changes in cudf/pull/13372, and adds explicit
null-count calculation for the string offsets column.
