enable/disable distiller also all item into chrome menu and enables reader mode.
I guess goal to to change print preview and not that behavior.

So this switch should be next to other print preview switches

Currently, --enable-dom-distiller activates/deactivates both the Simplify page
checkbox (print preview) and Distill Page (reader mode, chromium menu). Should
we create a new flag then, just for print preview and not consider
--enable-dom-distiller altogether?
