Feature to display the output of a render pass directly in the 3d viewport rendered shaded mode.
- In the rendered popover the user can select the render pass to be shown
- This will be available for all render engines that have multiple render passes
- Also possible to select renderpass that have not been enabled in the active viewlayer.
- by default the first renderpass will be selected (Combined pass)
The implementation will be based on T68312: LookDev & Eevee Preview.
