[WIP] Enable inline usage of flexform data viewhelper

Useful in combination with ``v:content.get`` or other situations where raw records (arrays) are available.
> Plus $table and $field are not required when used inline

Hmm. Table and field are *always* required. The way this works internally is it resolves a Provider, and it is this resolving that requires the table (cannot assume default of `tt_content` since it is equally likely to be a page template) and without the field, you would perhaps not resolve the correct Provider.
