Do we really want to make QC know that _modin_frame has _row_lengths? Same question got hung in #4460.

@YarShev Why not? The modin is based on this mechanism, in addition, this information can be used to advantage in some functions. I think that we can make these functions public (_row_lengths/_column_widths).

I am okay with this (link) but @devin-petersohn, @mvashishtha might have different thoughts on the matter. I would like to make sure we are on the same page.

I support making row_lengths and column_widths public.

Good, let's make those public. Please create an issue for that.
