Fix T79127: crash on `scene.ray_cast()` with non-viewport view layer The `rna_Scene_ray_cast()` function tried to find the current depsgraph. To this end, it required the scene, the view layer, and bmain. Scene has a cache of per-view-layer depsgraphs, to speed up switching between view layers. This cache does not contain render depsgraphs, and evaluated view layers also don't have a depsgraph here. When a suitable depsgraph cannot be found, a new depsgraph is created. However, this depsgraph is not evaluated, and has an unexpanded scene pointer with a `NULL` `view_layer`. Using this then crashes Blender. Also, there was no way for the code to get the render depsgraph. The solution is to pass the depsgraph to the `ray_cast()` function, instead of the view layer. This avoids the depsgraph lookup, and also works correctly when rendering. Some add-ons also need updating, which I'll do in the `addons` repository soon.
