The skip records API added to the ArrayReader trait as part of #1998 does not provide a way to combine multiple selections into the same batch. This is unfortunate as columnar query engines will often want consistently large RecordBatch so that any dispatch overheads can be amortised over many rows. Whilst it could concatenate batches together, e.g. DataFusion's CoalesceBatchesExec, it would be more efficient to do this directly on read and eliminate an additional copy.

Ultimately doing this is supported by the underlying machinery, i.e. RecordReader, it just isn't exposed by ArrayReader

Describe the solution you'd like

Much like RecordReader we need to separate read_records from consuming the resulting data, i.e. replace ArrayReader::next_batch with ArrayReader::read_records and ArrayReader::consume_batch.

Describe alternatives you've considered

We could not do this, however, if we are going to make this change we should probably do it before we make the record skipping API public (#1792)
