Goal of this refactoring is to represent enumerations of socket via its declaration.
Instead of support some certain nodes with definition of enum in its, propagate
enum references from source sockets which is know its own enum.
Now, to add new enum definition to node ui, declaration of socket just required.

Generally i like the idea, but requested some changes/clarification.

Is this a fix for a different problem? I don't see how it's related to the enum items propagation below. Why is it here?

This flag is currently used to avoid unnecessary updates when the node hasn't actually changed. A node tree update can happen for any number of reasons, and if the enum items haven't been changed it should not cause ripple effects by propagating "new" enum definitions. I don't see an equivalent check in the new code. Should be possible to include this after the is_enum_source condition?

Generally, there is needed some kind flag of nodes to propagate changes state from updated node with enum-source socket.
At the current state of PR, i am not sure if such simple check is enough.
