feat: bucketed scan for native_datafusion Parquet scan

[mbutrovich]

What is the problem the feature request solves?

The native_datafusion Parquet scan does not support bucketed scan, and fails most of the tests in Spark's BucketedReadSuite without a fallback. With a bucketed scan, some partitions end up without a file to read so their PartitionedFile is empty.

Describe the potential solution

I don't think DataSourceExec will take no file at construction. We might need to replace that node with a different no-op node that generates an empty data set with the correct schema in the case of a bucketed scan when a partition has no corresponding file.

Additional context

Interestingly, native_datafusion currently passes the "bucketed table" Comet test. I suspect the Spark SQL tests are doing some bucket pruning, which is where we end up with empty file paths for some of the partitions.
