Workspace: Move engines to workspace and Properties Editor cleanup

Engine is not stored in WorkSpaces. That defines the "context" engine, which
is used for the entire UI.

The engine used for the poll of nodes (add node menu, new nodes when "Use Nodes")
is obtained from context.

Introduce a ViewRender struct for viewport settings that are defined for
workspaces and scene. This struct will be populated with the hand-picked
settings that can be defined per workspace as per the 2.8 design.

* use_scene_settings
* properties editor: workshop + organize context path

Use Scene Settings
==================
For viewport drawing, Workspaces have an option to use the Scene render
settings (F12) instead of the viewport settings.

This way users can quickly preview the final render settings, engine and
View Layer. This will affect all the editors in that workspace, and it will be
clearly indicated in the top-bar.

Properties Editor: Add Workspace and organize context path
==========================================================

We now have the properties of:

Scene, Scene > Layer, Scene > World, Workspace

[Scene | Workspace] > Render Layer > Object
[Scene | Workspace] > Render Layer > Object > Data
