[IMP] web: support action helper on gantt view

Currently, only List and Kanban view supports the action helper and
display the folder icon with the helper text.

With this commit we have also provided the action helper support for
other views. The logic for no content helper has been moved in
abstract_renderer.js so that it can be accessed by all views. This was
done mainly to give the action helper to the gantt view.
