New data orented idea: Node/Scene Instances

[Shadowblitz16]

This has to do with the issues like particles not being entirely configurable though it's particle material, and things like animated sprite not being entirely configurable through sprite frames resource.

What if instead of having a set type of resource for certain types of nodes you guys move everything to the node and give us the ability to export the node's properties to custom resources?

For example for particles the particle material resource would be removed and made part of the particle node, and then users can create a instance out of their node or scene and mark what properties are editable form the resource.

This would go along great with being able to forward properties to the local scene root.
see.. godotengine/godot-proposals#6750

Properties could be generated by using codegen

The idea is similar how unreal engine has instances but the idea is that instances would just be a config file for a certain type.
The actual object could be handled through something like a instantiate method on the instance or a property on the Node class

Another idea is to do the above but instead of moving the particle material properties to the particle node you can actually make it a render material, then we could forward it's properties to the node/scene instance
