Description

In ARROW-14745 we thought about having to_arrow() returning a RecordBatchReader only. Though this would work, it's not quite as friendly as wrapping the RecordBatchReader since {{arrow_dplyr_query}}s have a (slightly) nicer print method.

We should add more methods and a print method that makes it clearer what a RecordBatchReader is and what it might be useful to do (e.g. continue a dplyr query)

Is it possible that we could make up a name/class that encompasses all of the Arrow tabular like things that we could wrap all of these up in (for UX purposes only, really). We have ArrowTabular now, maybe we lean into that more (along side an LazyArrowTabular like dbplyr has?).
