ARROW-17631: [Java] Propagate table/columns comments into Arrow Schema (#14081)

Allow user to provide comment in Arrow Schema from  JdbcToArrowConfig . It will be very useful metadata in real life (medium to large scale project) for documentation and maintenance topics. Apache Spark code use "comment" key for such metadata, so this looks like reasonable default name for metadata in Arrow schema too
