[2.0.9] Views Rows source improvement : rows are arrays of visible fields when "force using fieds" is checked

Problem/Motivation

This may be useful, to be able to use the views rows source in a new manner.
Indeed, today it returns an array of renderable. Each of those renderable is a row (such renderable may be of type views_view_field for example when one select fields as row style plugin).

Why not adding an option that allows to convert each row as a table of fields?
this allows to more easily inject this data into the slot of a table component for example,
where such component slot could expect an array of depth 2 (depth 1 = row, depth2 = cells)
