[ARROW-9595] [Java] DefaultVectorComparators does not have a comparator for BaseLargeVariableVector

• Type: Improvement

Description

The method

org.apache.arrow.algorithm.sort.DefaultVectorComparators#createDefaultComparator

does not handle vectors that are instances of BaseLargeVariableWidthVector

It would be nice to extend this method to handle this case. It looks like it ought to be easy to define an appropriate comparator class

class LargeVariableWidthComparator extends VectorValueComparator<BaseLargeVariableWidthVector>
