FIX More context for GridFieldDataColumns callbacks

This emulates the callback signature from
GridFieldEditableColumns in the symbiote/silverstripe-gridfieldextensions module, which extends GridFieldDataColumns. In case canEdit() fails, this component passes control back to the parent (rendering a standard column content rather than a formfield). Which can become an issue if you've defined custom 'callback' handlers on setDisplayFields() - GridFieldDataColumns passes in only one arg (`$record`), while GridFieldEditableColumns passes in three (`$record`, `$col` and `$grid`).

While you could argue that this is a bug in the other module,
I think this additional context is beneficial for the main
GridFieldDataColumns use case as well, and it just happens to fix that bug.
