Description
Fixed an issue in the Parquet writer where all compression would fail when device compression with internal kernels is used.
Root cause is that a compressed chunk size was not being set, as it's not required for the nvCOMP implementation.
Expanded a few tests to use internal kernels for compression; planning to make more extensive test changes to improve test coverage of compression/decompression internal kernels in a separate PR.
