Nodes: Duplicate Linked operator + User Preference option for Node Tree

This operator (Alt + D) allows users to explicitly create a linked copy
of a group node (same current behaviour for the Duplicate operator).

The duplicate operator (Shift + D) now takes the new User Preference
duplicate data option for Node Tree into account. It is by default
disabled, leading to no functional change for users.

Although we could make in the future make this option "on" by default,
to make it consistent with the rest of Blender we do not at the time.
