Description

The is_in_meta_binary and index_in_meta_binary functions do not have any "_doc" elements. I had simply ignored them assuming they were some kind of specialized function that shouldn't be exposed for general consumption (see ARROW-13949) but I recently discovered they are legitimate binary variants of their unary counterparts.

If we want to continue to expose these functions we should rename them (meta I assume means meta function but the python/r user has no idea what a meta function is) and add _doc elements.
